Also getting this error on my app since compiling in 6.2.7.
Which stops execution.
Are you installing as administrator?
If you ignore, what happens?
This issue is unrelated to the original thread. Could you post it on its own thread - also, could you post a screen shot of any error message? You note there is an error, but do not say what it is.
Re-installed as administrator but no different. Brings up 3 files unable to rename similar to the above error. Appstudio seems to run and compile fine. Since installing again the changeform error I mentioned is no longer a problem. So I'm all go with seemingly no problems. Cheers.
