I've been testing out various solutions using Powershell to list installed program information, which is fine more most information such as version info, etc but the key piece of info I'm looking for is the InstalledLocation/InstalledDir. It seems that in most cases, this particular property is simply not available for most programs. Given a program name (displayname), can someone suggest a way to reliably/efficiently get a program's installation directory/path (remote to other servers)?

Thanks in advance

Thank you Simon. Under the covers, that solution still uses Get-ChildItem, which is what I've been using. The problem is that many of the third-party installers don't set the InstallPath property. So, nice procedure but doesn't fix my issue.

maybe a combo of a wmi query and a registry query needed.

I have a few ITIL level questions (as these lead to a lot of places to look):

1 – Are you saying, these 3rdP installers do not even register themselves in the Add Remove Programs and do not provide an uninstall path? If so, then, how would you uninstall them?
2 – Do you have a ITIL/CMDB SOP, that list the allowed to be installed applications, aka whitelist?
3 – How do these apps get distributed / installed?
4 – Do, you have a ITIL/CMDB SOP, the scan's and records the systems environment variables and subdirs of those?
ProgramData C:\ProgramData
ProgramFiles C:\Program Files
ProgramFiles(x86) C:\Program Files (x86)
ProgramW6432 C:\Program Files
5 – Do, you have a ITIL/CMDB SOP, the scan's the systems registry for all uninstall strings?
6 – What about AV scan polices, does your ITIL/CMDB policy define scan locations? (I ask this, because if the AV is scanning, then it should have a log of what it scanned and the result of that scan.)
