Autosave counter 2.05, when attempting to create a save (during the "unzipping" stage), produces the following error:

"Failed to launch the program or component gzip.exe due to incompatibility with the 64-bit version of Windows."

After this, the save file it was re-saving is deleted, and a new one appears with the correct name and a size of zero kilobytes.
I am using Windows 7 64-bit.
Running it in compatibility mode did not help.

Does anyone know how to fix this?
