Hey everyone,
My PowerShell experience is limited, so bear with me a little bit here. I’m trying to create a package for Adobe Acrobat DC 2017 Classic 17.011.30070. During the pre-installation step, I want to uninstall all previous versions of Adobe Acrobat. Normally, I’d just use Remove-MSIApplications -Name ‘Adobe Acrobat’, but Adobe, in their infinite bleeping wisdom, names the equivalent version of Adobe Reader “Adobe Acrobat Reader blah blah blah”.
So I created a simple RegEx to avoid matching Adobe Reader installations. Here’s the code I’m trying to use:
Remove-MSIApplications -Name ‘Adobe’ -FilterApplication (,(‘DisplayName’, ‘Adobe\sAcrobat\s(?!Reader)’, ‘RegEx’))
I know this RegEx works outside of the App Deploy Toolkit, but it doens’t match anything when using it inside of the toolkit. So I dug into “AppDeployToolkitMain.ps1” and discovered this:
If ($installedApplication.($Filter[0]) -match [regex]::Escape($Filter[1])) {
Doesn’t [regex]::Escape() tell PowerShell to ignore regex in the string inside the parenthesis? So this would effectively neutralize any RegEx I’m trying to pass. Is this a bug or are regular expressions just not supported here? Is there a better way to accomplish what I’m trying to do?
I suppose I could just put my own code in the pre-installation phase, but I trust the toolkit a little more than I trust myself. This is the code I would have used in my own scripts:
Get-Package | Where-Object {$.Name -match "Adobe\sAcrobat\s(?!Reader)"} | Foreach-Object {Uninstall-Package -Name $.Name -Force}
I appreciate any responses, thanks!
