I have now solved the issue, but what the problem was as follows, I have the Mac version of AVStudio and I needed to create an .exe version to play on a windows PC so I used the "safe Executable for PC" and this creates a zip file, When unzipped it reveals 2 files, an .exe of about 14mb and a pteav file of the size according to the AV content.
I thought that the .exe file was to play on a windows PC and the .pteav file was for a Mac.
I have since discovered that BOTH the .exe AND the .pteav files must be in the same folder in order to run on a win PC, I was just trying to run the .exe file without access to the .pteav so my problem solved.
Just a suggestion though that this is not made known when publishing the AV so a few words to that effect in the 'Publish' panel would be of help, what it says now is "Exe file in zip with a digital signature" which is not at all creating to me what this means.
Hope this is clear to you
