Hi,

I have a scmall C# script use to execute scripts in photoshop. this program use

Activator.CreateInstance("Photoshop.Application.190")

if photoshop 2025 is not open, it works fine, if photoshop 2025 is already open it fails and return null

also why is it Photoshop.Application.190 instead of Photoshop.Application.26 and where are thoses versions for the COM documented ?

Thanks

    more info the bug might be trigger by the fact that Activator.CreateInstance("Photoshop.Application.55") has been called previous to calling Activator.CreateInstance("Photoshop.Application.190")

    we are trying the versions from older to newer.
