I had this kind of case as well when i was messing with the infozip library in the past.
It seems that code 1 is used when the program does everything without receiving system errors but doesn’t find an output file as result.
Or it retreives a system error that it doesn’t have a mechanism for.
I’m running it on 64-bit windows called from within in a 32-bit application…
Not in particular, is it voiding “com.renoise.xxx” toolnames through this way perhaps? (copied the tool to the MyTools folder)
I also made one change to the API versioning inside the creattool mechanism (Because the tool was still attempting to save tools as API 1.0) but i changed that back to see if it made a difference, unfortunately not.
In my case it tried to access the Documents and Settings folder… which no longer exists on Windows 7 64 bit, but the tool had it saved in its preferences file
