Hello
I have a problem with my Mazak QTN 200 MS 2004 model which runs mazatrol 640T PC fusion. Mazatrol wont open and it comes up with this program has performed an illegal operation and will be shut down
I am hoping to back up the Sram before I get the HDD out and clone it. Because I can't open mazatrol I can't save the Sram files using the standard procedure. Does anyone know if there is a way to do this without opening mazatrol 640T on Windows 95?

We tried saving via Mainte.exe found in windows explorer (I think) but it wouldn't run. I assume Mainte.exe is related to Mazatrol.
There are PLC ladder and parameter files on C drive which date back to when the machine was new. We have saved these to a USB stick but if I understood correctly a Mazak tech told me the original data might be out of date.

Computers are not my strong point so please forgive me if I don't know what I am on about.

you can try to boot from USB stick.
Is it Windows 95 ? Did you try to clean up ( register and system partition )
