Uninstall.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Uninstall.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like bypass_client_win32.exe - to follow. These files were created so that multiple programs (eg. Bypass Proxy Client) could share the same Uninstall.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when Uninstall.dat is attempted to be loaded either when Bypass Proxy Client is starting up, or in some cases already running. Some of the most common Uninstall.dat errors include:
- Access Violation at address - Uninstall.dat.
- Uninstall.dat could not be found.
- Cannot find C:\Program Files (x86)\Bypass\Client\_uninst\Uninstall.dat.
- Cannot register Uninstall.dat.
- Cannot start Bypass Proxy Client. A required component is missing: Uninstall.dat. Please install Bypass Proxy Client again.
- Failed to load Uninstall.dat.
- The application has failed to start because Uninstall.dat was not found.
- The file Uninstall.dat is missing or corrupt.
- This application failed to start because Uninstall.dat was not found. Re-installing the application may fix this problem.
Your Uninstall.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Bypass Proxy Client), or deleted by a malware infection. Furthermore, Uninstall.dat file corruption could be caused from a power outage when loading Bypass Proxy Client, system crash while loading Uninstall.dat, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
