@Mustaq: This guide was written for Windows 10. At your case (windows 7 32bit) first check your computer for malware and then try to run your DOS application in clean boot state. If the DOS application doesn't run then execute the below 2 commands (in Command Prompt Admin mode) to repair system files:1. Dism.exe /Online /Cleanup-Image /Restorehealth2. SFC /SCANNOWp.s. If the DOS application run without problems in "Clean Boot State" then some application that load at startup (e.g. antivirus) cause the problem.
Restoro is a complex Windows system repair solution that scans your PC for various issues and fixes all critical system files and registry errors, as well as the damage left by viruses (not antivirus software). With a few clicks, the program frees up space on your disk and restores all compromised Windows settings to their default value. 2b1af7f3a8
