I recently migrated from ISE 12.3 to 14.5.
I also moved the project location ( to a directory with spaces in the path name).
I use impact to generate bin file from the bit file.
The first time running impact, it gets the ipf from the old location.
I changed it to find it in the new location.
Then it cannot open the ipf file.
I then manually open the ipf file.
It then works one time and then fails on subsequent tries.
It also works one time for every time I re-copy the ipf file from the old directory.
Each time I have to point at the new location for the bit and bin files.
I tried saving the impact project file (to the new directory), it doesnt help.
I can generate the bin file, but upon exiting impact it gets an error "ACD entry not found"
So each time I have to copy a new ipf, point at the new directory for bit and bin, generate, crash.
I tried to file, new project but that doesn't work either.
