I had the same problem.

host: Debian 10.2 (buster) x64
guest: Windows 7 Ultimate x64

In my case, installing the Guest Addition on the test build did not cause an error, but the following problems remain in Windows 7 Guest after that.

- The choice of screen resolution is limited.
- The mouse integration function does not work.
- Explorer dies when trying to view display properties.

These worked fine in 6.0.14.

Finally, I successfully installed build 6.1.1 r135516 with working GA incl. 3D.
Thus can confirm socratis statement.
Thanks for your help.

Greetings,
Tom

PS
Please, correct the codepage glitch.

Thanks Socratis and Tom, for your feedback!

@Tom Please have another try at test build r135531 which you again can find at the test builds page. This hopefully should also resolve your issue. Thanks!

Edit: I had this draft saved for a couple of days, i completely forgot all about it!

That's a key point...

If I try it on a Win7-32 VM it works just fine, if I try it on a Win7-64 VM it fails with a:

Oracle VM VirtualBox Guest Additions has stopped working
Windows can check online for a solution to the problem.
➡ Check online for a solution and close the program
➡ Close the program

BTW, did someone forget a "1" in the Module version? And instead of "135514" it shows as "35514"?

Actually, even though it works fine on my Win7-32, it seems that something broke in a Win10-64 (1607) GAs installation...

Version 6.1.1 r135485 (Qt5.6.1), GAs r135482 => Works just fine
Version 6.1.1 r135516 (Qt5.6.1), GAs r135514 => Failure

Will try with the new test-build and report back...

All is well with recent testbuild 135531 (GA:135519)
Thanks for your efforts.

@Tom Glad to hear that, thanks for verifying!

• WinXP-32: works
• WinXP-64: works
• Win7-32: works
• Win7-64: works
• Win10-32: works
• Win10-64: works

Notes:

• Win7-64 took an unusual time to get the installation done.
• I've lost SharedClipboard on both WinXP-32 and WinXP-64. But that's not to be resolved here.

1. Uninstall current Guest Additions in the guest using Control Panel/Uninstall a program
2. Reboot
3. Install the new addiitons

This should fix the error. At least it did here.

For what it's worth, I had the same problem as described in the OP; following these steps allowed the installation to complete successfully.
