Error message when opening a project: Project is write-protected
If, after installing other software (in particular MS Office), when opening a project in SIMATIC S7 T Config, SIMOTION SCOUT, STARTER or Sizer, you get the error message indicating that the project is write-protected or already open, it might be possible to clear this situation with a repair or an update of the "Microsoft Access Database Engine".
For example, the following error messages might appear:
S7 Technology, Scout, Starter or Sizer DVD or from the unpacked installation package and then selecting "Repair" followed by "Fix Errors".
The "ACERedist.msi" file is in the setup directory under "...\InstData\CheckRequirements\Media\setupdir" or, for STARTER V5.3 or later, in "..\InstData\CheckRequirements\Media\setupdir\AceRedist_2010_x86".
Restart your computer after the repair.
