Possible serious Registry issue in InstallAware 15

[miha96ac]

Hi!

I just upgraded my InstallAware installation from NX to 15 - and compiled my install script on 15.

In this script I have a line where I grant EVERYONE read + write access to a registry key - which includes another registry key with registry values.

When running the installer compiled in IA 15 - the permissions to my registry keys are somehow applied wrong. When the permissions are viewed in REGEDIT they are applied as "Special permissions" and I cannot access the keys properly and it is impossible to delete or even rename the keys even as Administrator running under UAC with full permissions.

Luckily I had a snapshot of my IA NX installation - and to be sure that it wasn't a bug I had introduced in my script - I compiled the exact same script on NX again. This time all registry permissions are applied correctly and REGEDIT shows the permissions applied as "Full Control" - which leads me to think that IA 15 has an issue with applying permissions to registry keys.

I tested and verified this issue on Windows 2008R2 and Windows 2012.

This is quite a serious problem - as all subsequent installations of my program will fail because of the this issue - and also the uninstallation of the program fails with an error message saying it cannot access my registry keys.

I am (to my knowledge) not running the native engine (the script has pretty much stayed the same through a number of IA updates going back to 2008).


Thought you might want to know about this - and hopefully replicate and fix the issue.

Best regards,

Michael

Dear Michael,

I have tried to replicate your issue with WIN 2008 R2 but seems to work fine with my test environment.

The permission are applied as "Special permissions" to Everyone, I have full control over the key and I can modify the REG KEY permissions settings as well (UAC Enabled).

Did you used a particular REG KEY path? With my test I used a key under HKLM\Software.

Let me know.

The permission are applied as "Special permissions" to Everyone, I have full control over the key and I can modify the REG KEY permissions settings as well (UAC Enabled).

When during this in IA NX and previous versions - it is applied as "normal" permissions.

My registry keys are located under HKLM\Software\<subkey>\<subkey that is being given permissions>\<subkey>

I tested and verified 4 different installer builds on IA 15 - on 2 machines - all experienced the issue. Running the uninstall feature resulted in an error - only option was to revert the virtual machines to previous snapshots.

Rebuild the installations on IA NX - and everything worked fine.

Dear Michael,

could you post a very minimal project that replicate the issue?

Dear Michael,

I have just completed a test with IA NX and I haven't found the same as you.
