Delete Registry Key not working

[tmeltran]

Hello - during un-installation, I want to remove registry entries that were created by the application post-installation. From the help it seemed simple, call Delete Registry Key before Apply Uninstall, shown in the attached screen shot. But it doesn't work.

I've also tried adding the blank key under Setup Architecture\Registry of the Design tab, which was also suggested in the help file. That doesn't work either.

Any suggestions would be much appreciated.

Dear User,

I have just executed a quick test over a test REG KEY under HKCU and it worked fine.

I used the call to Delete Registry command just after Apply Uninstall but, because it is a Direct execution command, it can be called anywhere.

For your convenience I used the following parameters with my test:

Code: Select all

~InstallAware Clipboard Data~
~Delete Registry~
~{7B97DE63-3227-4138-AA21-E013E2668C72}~
~1~
~Software\MyCompany\MyApplication~
~~
~TRUE~


Code: Select all

Delete Registry KEY HKCU\Software\MyCompany\MyApplication\*.*


Let me know.

Regards

Same problem here.

Trying to delete registry entries under HKLM\Software\<manufacturer>.
This succeeds when there is a key with values but NO subkeys.
If there are subkeys under the key to be deleted, it does nothing.
This happens on 64bit Windows 7 after setting the installer to 64bit mode.
In 32bit mode it seems to be working as expected.

Dear PaavoN,

I just verified and with my tests the Registry key deletion under HKLM works fine.

I used WIN 7 x64 and a native 64bit mode setup package, to verify the registry key deletion where several sub-keys are present.

If you can reproduce the issue with a very basic project, I will be happy to verify it.

Regards.

Hi Francesco

Find below a test script I used to verify this.
Attached is also a reg file which I used to produce the reg entries.

This works in 32bit Windows 7 but not in 64bit Windows 7 and not in Windows Server 2008 R2.

Dear Paavon,

just to inform you that this issue has been logged to our fix list.

Has this been fixed? It seems to not work for me using v18 build 7.1.14

[tcgielow]

CORRECTIONUpon further testing it is indeed working. My placement in the MSI code was a bit off and it took my brain a bit to catch up.
