I believe I've found the issue: replacing the leading "\\" with "*\" seems to work for executable & target executable file path.
What happens if I do this on my local PC?
not a big deal if you are using signer and or file description and or hash... but someone folks may consider wildcarding and I just want to have folks consider the ramifications...
would using ?\servername\sharename\subfolder\subfolder\executable.exe work in your environment? Might be safer, maybe?
