Open a command window and see if someone alters the windows path to not include a path to that .exe.
Also, you didn't tell if the rstrui.exe existed. I see you "tried" things but didn't share much besides it didn't fix the issue. For example the output of the expand command could have been Can't find C:\i386\... Which would have me ask what's in your \i386 directory, etc.
I have Fujitsu Siemens Laptop and when I tried to open the system restore the following msg pop up windows cannot find c:\windows\system32\restore\rstrui.exe i thought the system restore is not active but it was already activated
I have tried many ways to solve the problem but none worked which are:
- Reinstall the Sr.inf in the safe mood
-Delete the rstrui.exe in safe mood and reactivate it by reinstall the sr.inf
-expand c:\i386\rstrui.ex_ c:\windows\system32\restore\rstrui.exe
and I use antivirus to find if there is any virus but it found none
so is there any way to solve this problem?
