hi

i am trying to run the below vb script to uninstall msi (x64/x86) using "DISPLAY NAME" in windows 7 (x64) but looks like the below script doesn't like the DISPLAY NAME called (Pulse Secure). But if i change the name of DISPLAY NAME to "Pulse Sec" or "Secure Pulse" etc. it works fine. So i am just thinking to see why it doesn't like "Pulse Secure" name?

any help should be appreciated

I know I said I retired but I was here, had time, so....

Phil's right, use the WI object model.

As an exercise, though, o come to the problem, I think the issue is with your use of the Regular Expression object. Using that is fine and all when you're dealing with unknown or variable return values but here, you know what you're expecting back so why not do a simple case-less string and string length match? In pseudo-code:

If input_string_length matches registry_string_return_length then
If input_string matches registry_string_return then
'// Bingo! Uninstall it
Endif
Endif

PS:

Please apply the 'Code' style to your code. It makes the post more manageable.

Hi,
why not just use the Windows Installer API via COM (if your language is vbs)?
It's allot less convoluted and you do not need to worry about 32/64 bit as you'll be de-installing using the product code..

I can only assume you're scanning the ARP keys for Pulse because you can't trust what the product code is going to be. I am also in a project to deploy PulseSecure and recently discovered what I consider a very odd behavior. The product codes change mid install depending on what region the installer detects. So far I am aware of 16 different product codes for 8 different regions. Obviously, 1 for each OS architecture. Pulse has suggested they will release these product codes in one of their next Release Notes. I would offer the ones up that I have, but I have no idea what version you're dealing with, so they might be totally irrelevant. Their support is actually quite helpful when engaged, they only took about 45 minutes to produce the codes when I started seeing issues with global deployments.

  • I should also state that I dealt with the multiple product codes by placing them in an ini and having my install\uninstall script cycle through them in a list. SCCM on the other hand was a PITA as it required 16 unique detection methods. I have a good reason for wanting the prod code for this VPN client rather than relying on the exe versions alone.
    • I had a similar problem with an InstallShield "wrapped" MSI, that changed the ProductCode dynamically, always, regardless :-O

      I completely repackaged that in the end... (I know you should never repackage an MSI, but I did not consider that a MSI ;-) )
