Hello. You have a few complications here. One, Win 8 is brand new and you are putting it in parallels. I am not surprised there is a conflict as the configuration you are using to try to run this is so new- we are talking weeks old and our software was released 8 months before this config was available.
But this is a licensing error, so it is sort of pointing to the licensing technology and not the program functions. I am guessing this is a standalone installation. Your serial is not the problem- likely a registration file.
Let’s try to reregister:
We are looking for a specific TSF file. It will resemble this: ADSKFLEX_NUMBERS_TSF.data. It should be located here:
Vista/Windows 7/maybe Win8??:
Find this data file and change the extension to something different, like ADSKFLEX_NUMBERS_TSF.data.BAK or completely move it from this folder. We don’t want to destroy it, just get it out of the way.
After it is moved or renamed, start the program. A new TSF DATA file will be created and possibly a log file. If the program now works, great, if not, delete the NEW TSF.DATA file and the log and place the original file back in this location, or rename back to ADSKFLEX_NUMBERS_TSF.data
Now try to start the program. If you are asked to register, do so and you should be set.
Thank you for taking part in our community!
