Error when saving with 2.0

Any idea of the meaning of this error message:
“Exception EFOpenError in module MyApplication.exe at 01F622F3”.

It happened when saving.The .EXE closed and the error message was shown.
After this I tried to open the same .EXE and Windows said the file was corrupted, Excel close again with another error message:
"Exception EReadError in module Myapplication.exe at 01FA1C9C.

When rebooting the PC the problem solved.
PC specs are:

  • Intel Core 2 Duo CPU T6500 @ 2.10 GHz
  • Windows 7 Professional 64 bits
  • Microsoft Excel 2010 Professional 32 bits

I am using the new versión 2.0 , hardware key.

EFOpenError means that the program could not open a file. Do you have an antivirus program that could interfere or corrupt the EXE file?

My client has informed me that he has the Avira Free Antivirus and the SpyBot Search & Destroy.

Try to disable these programs.
