Failed to create VirtualBox client com

Normal shutdown of VirtualBox a few days ago, today found unable to boot my system when OS X 10.10. This may be the result of the recent frequent VirtualBox upgrades.

Advice:
Provide a snapshot of the Linux virtual machine that is normally performing major configuration or project work

Error message:
VirtualBox client COM failed to create
Caller RC: NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154)

Try solutions:
Restart the computer;
Reinstall VirtualBox
Correct solution:
Access to the Internet caused by access problems.
Find my VirtualBox application is in/usr/local/bin/VirtualBox
Open the terminal operation failure directly, use sudo/usr/local/bin/VirtualBox can run. But this is inconvenient. You have to run from Terminal as root every time.
Find the solution on the VirtualBox website below:
The first step:
View permission information for/TMP directory:

/bin/ls -ld /tmp

The second step:

Sets the owner of the/TMP directory to root

chown root /tmp

Third part:

Change the access control permissions of the file owner and group, -s is to give suID permissions, ordinary users can also run as root permissions.

chmod ug-s /tmp

Step 4:

Grant permission to the/TMP directory RWX 777

chmod 1777 /tmp

Step 5:

Delete the old.vbox directory

rm -fr /tmp/.vbox-root-ipc/

Then start VirtualBox!

I. installation of Office2016 failed
1. Problem description
Office2016Another Installation is in progress…” Or error code 0-1018 when Installing Office, or the other installation is underway, “error code 0 ~ 1018”, etc
2. Error reason
The reason for this error is that we installed Office before and then improperly deleted it. For example, we directly deleted the folder, and used the third-party software which was not quite normal, so the uninstall was not clean. When the installation program detected the residual information of the system, it caused such a false impression that the installation failed
3. Problem solving
The solution to the problem is to completely uninstall the residual information of the system Office, specifically, to use the official cleaning tool of Office, which is relatively simple to use and no longer cumbersome. The repair software can be downloaded from the repair software of Office2016 (if invalid, please leave a message).
4. Tips
The best way to uninstall large software such as Office is through the control panel or Office uninstaller

Encounter: cannot open volume for direct access

One day, if you don’t know what software you have installed, it will appear in the boot process when you boot or reboot:
Cannot open volume for direct access.
Autochk cannot run due to an error caused by a recently installed software package.
Use the system restore feature from the control panel to restore
An unspecified error
boot time of my machine also jumped directly from 12 seconds to 29 seconds, and the self-check would automatically skip, without actually going to self-check.
After a random search, they all need to enter the safe mode for CHKDSK for detection and repair. I don’t want to go to such trouble. I always feel that my machine is not in such trouble.
here will repair method of Microsoft in the BBS links posted

https://answers.microsoft.com/en-us/windows/forum/windows_7-performance/chkdsk-error-cannot-open-volume-for-direct-access/5f8c4a7f-e609-445b-a63d-aa63f7112440 but, I still think, I did it because I installed the software. But why doesn’t the machine detect it automatically and skip it every time?
there must be a reason that pre-loaded software such as anti-virus software is preventing automatic detection (remember win95 to xp encountered similar things, but not automatically skipped detection), try uninstalling 360.
Sure enough, after uninstalling 360 and restarting the machine, the machine will no longer skip the automatic detection, and restart the machine after the successful completion of the detection. There is no longer any annoying reminder that Cannot open volume for direct Access.
machine startup time is back to 12 seconds.

VBA 400 error

Failure phenomenon: VBA small program, after running macro, sometimes can proceed smoothly, sometimes on the “wind”, 400 errors

Solution: There are a lot of things that could cause 400 errors, but my solution is strange, just activate the worksheet of the action. This object is probably caused by the use of thisWorkBook… This problem can be fixed by using thisWorkbook.sheets (“Sheet1”).activate.

Such as
Set objData = New DataObject
sHTML = Range(“E” & (I)). The Value
sHTML = Replace (sHTML, “& lt; br />” PutInClipboard
ActiveSheet.Paste Destination:=Range(“E” & (i))

As long as to
Set objData = New DataObject
SHTML = Range (” E “& amp; (I)). The Value
sHTML = Replace (sHTML, “& lt; br />” . PutInClipboard
thisworkbook.sheets (“Sheet1”).Activate
activesheet.paste Destination:=Range(“E” & (i))
I’m going to report 400 errors

VirtualBox start error NS_ ERROR_ FAILURE (0x80004005)

VirtualBox startup error NS_ERROR_FAILURE (0x80004005)


detail forgot the screenshot, the specific error message is NS_ERROR_FAILURE (0x80004005)
Causes:
(personally) During code debugging, for some reason the project’s log files filled disk C (my native Shared folder with vm was on disk C, crying… If you are using Windows, put the Shared folder on another disk), the virtual machine automatically pauses, and the forced exit occurs. After two forced exits, the 0x80004005 error occurs.
Solutions:

    find your virtualbox, or virtualbox shortcut on the desktop, right-click – > Property – & gt;
    after modification, open VirtualBox again, error message is as follows:
    the Document is empty.
    Location: “C:/Users/Administrator /./VirtualBox VirtualBox. XML ‘. The line 1 (0), column 1

Expected primary expression before ‘unsigned’ solution

statement result += unsigned int(1) < < i; can be compiled and run locally, but a compilation error appears after uploading to LeetCode: expected primary-expression before ‘unsigned’.
analysis:
statement is too complex, the compiler on LeetCode can not fully compile, need to add the basic expression.
solution:
1 for unsigned int add parentheses: (unsigned int).
2 add intermediate variable unsigned int one = 1; result += one < < I .

Cause: 1) not registering the. Net framework with iis (one of the causes: installed the. Net framework first, installed iis later)
2) Insufficient operation permission (Modify permission) for the site configured in IIS
Solution:
1) go to c :\Windows\Microsoft \ net \Framework64\v2.0.50727,
Reregister the.net framework: aspnet_regiis-i
with the iis command
2) IIS Manager –> Sites –> Corresponding site –& GT; Right click –> Edit Permissions – & gt; Security – & gt; Group or User Names –& GT; Edit – & gt; Add – & gt; Add the Everyone user who is granted Full Control permissions (essentially Modify permissions)

Reproduced in: https://www.cnblogs.com/Jian-Zhang/p/6054770.html

There is a solution to the problem: severity = corrected, type = physical layer, id = 00e5 or id = 00e8 (receiver ID) under Ubuntu

I press CTR + Alt +F1 or F2 on Ubuntu and the screen flashes repeatedly as follows:
PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e8(Receiver ID)
As the search on the Internet, I found only: https://blog.csdn.net/qimengxingyuan/article/details/80874314?utm_source=blogxgwz2
His id=00e5 is different from mine, but I can’t find it. Follow the instructions:
——————— 
Specific operation
Edit the grub
Sudo gedit – H/etc/default/grub
Add boot option
Find GRUB_CMDLINE_LINUX_DEFAULT = “quiet splash.” ”
Add behind pci = nomsi pci = noaer pcie_aspm = off
— — — — — — — — — — — — — — — — — — — — —
I am in GRUB_CMDLINE_LINUX_DEFAULT = “quiet splash” added after the concrete is:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” pci=nomsi pci=noaer pcie_aspm=off
I tried it and it still didn’t work, And I thought I made a mistake and I tried it a couple of times and it still didn’t work, and finally I saw this
https://askubuntu.com/questions/863150/pcie-bus-error-severity-corrected-type-physical-layer-id-00e5receiver-id
Oh, I finally found it. It was my wrong way to modify it. The correct modification is as follows:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pci=nomsi pci=noaer pcie_aspm=off”
Then, as described in the two blogs above, perform:
1. Save the modification and exit
2, execute sudo update-grub
The 3, reboot
is now complete.
thanks for the above two detailed records
