Opening an app. by clicking its files results in error

i want dopus to open an application called tvpaint animation, when double clicking files with its extension (either .mir .tvp or .dip)
however if i try it i get an error message panel titled "tvpaint animation"
saying:
"tvpaint.loc
file not found(123)"
when i click ok i get a new panel with the same title
saying:"local file not found"

and the app won't open.

i have dopus 8.2.2.5 and win XP

in the system file types action tab
i did make sure all 3 extensions are pointed to open, in the right location, the tvpaintanimation.exe file

what could be wrong?

Did you put quotes around the %1? If the filename or path contains spaces then it may cause this sort of error unless the %1 is quoted.

Eg,

tvpaintanimation.exe "%1"
