Hello Sly Espina,
Did anything change with your computer since your Simatic Step7 sofware quit working? Did you add any software or install any Windows Updates?
If possible, you might try and see if you can go back to a System Restore point.
To choose a System Restore point,
· From the Desktop click the Pearl (start) button
· In the Search Field type “System Restore” and hit enter
· Once System Restore is open, select the option “choose a different restore point” and hit next
Once on the next screen, pick a restore point to go back to when it last worked for you. Once you select the restore point, click next, then select finish, this will start the restore process.
If you have some dlls that are not working correctly, you can try and register them.
Go to Start,
regsvr32 <path & filename of dll or ocx>
Please reply back and let us know if this helps to resolve your issue.
Sincerely,
Marilyn
