Removing / Uninstalling Virtualbox from Vista machine

Postby Symon » 4. May 2008, 05:41

Hello,
Would appreciate some help. I just installed the latest version of Virtualbox (1.6) on a vista Home Premium machine. I have tried everything to make it work. All I get is a blank screen, no errors. I would like to remove it completely from my pc, using add / remove programs. However, I'm getting the following error. "The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2738"

Help!

Thanks,

Symon

The VirtualBox 1.6.0 installer uses a VBScript custom action which has known problems on Vista. See http://www.joyofsetup.com/2007/06/07/wh ... more-evil/ for workarounds.

I got the same problem when i found the addon of 1.6 are much worse than 1.56, to be frank, and i decided to roll back to 1.56. this really made me nuts.

Dear Sun, could you please release the uninstaller?
or any way to remove it.

Error 2738 when uninstalling virtualbox 1.6 from vista

Postby nabamer » 9. May 2008, 01:40

Here is the fix so you can uninstall virtual box 1.6 properly in vista

run "regedt32.exe" in dos box then delete these 2 keys below:

"Check that vbscript.dll and jscript.dll aren't registered in HKEY_CURRENT_USER (HKCU), checking for the registry keys below.

* VBScript, HKCU\SOFTWARE\Classes\CLSID\{ B54F3741-5B07-11CF-A4B0-00AA004A55E8}
* JScript, HKCU\SOFTWARE\Classes\CLSID\{ F414C260-6AC0-11CF-B6D1-00AA00BBBB58}

Remove these keys if they exist in HKEY_CURRENT_USER. "

After I did that, uninstall worked properly.

Hello,
Thanks for all the suggestions, work arounds etc. I became really annoyed, impatient and disappointed with this product, and have decided not to pursue it any further by removing it from my system.

I had major problems uninstalling / removing it from my vista pc. I tried restoring prior to the installation several times, but that too failed. I was ready to trash my brand new computer because I was so mad!

However, consultation with HP Tech Support guided me through successful restoration prior to the installation, using safe mode. I'm a happy camper again.

Cheers!

As soon as v1.6.2 is out, please do the following steps to get a proper uninstall of 1.6.0, if the problem still exists:

- Copy the 1.6.2 VirtualBox.msi to your local disk (say C:\VirtualBox.msi)
- Open a command line window
- Go to C:\ ("cd C:\")
- Run command "msiexec /fv VirtualBox.msi"

This should replace the 1.6 uninstaller with the fixed 1.6.2 one. After that, uninstallation should work as expected.

Removing / Uninstalling Virtualbox from Vista machine

Postby pconne » 30. Jun 2008, 11:21

Hello,

I deleted the 2 keys:
* VBScript, HKCU\SOFTWARE\Classes\CLSID\{ B54F3741-5B07-11CF-A4B0-00AA004A55E8}
* JScript, HKCU\SOFTWARE\Classes\CLSID\{ F414C260-6AC0-11CF-B6D1-00AA00BBBB58}

and the uninstall process worked allright. Thank you

Now is it necessary to reimport those 2 keys into the register ?

Ph.C.

I figured how to uninstall it (version 2.2). I just went into add and remove and did a repair of installation and rebooted computer and then tried uninstalling again and it worked.
