Before running:
certutil -hashfile dsyadmvc11preqexeinstallv.exe SHA256
Compare with known hashes from the vendor.
Run in a sandbox or Windows Sandbox first if untrusted.
To extract safely:
dsyadmvc11preqexeinstallv.exe /? # check for help
dsyadmvc11preqexeinstallv.exe /extract # if self-extracting
Most prerequisite EXEs are poorly tested for all environments. Common failure points:
If your dsyadmvc11preqexeinstallv doesn’t run, check Event Viewer (Windows Logs → Application) for .NET or MSI errors.
dsyadmvc11preqexeinstallv.exe /log install.log /quiet
If /quiet doesn’t work, try:
dsyadmvc11preqexeinstallv.exe /?
Often, custom installers support /S (silent), /verysilent, or /norestart.
| Area | Current (poor) | Better approach |
|------|----------------|------------------|
| Silent mode | None | Support /quiet or /verysilent |
| Logging | None | Generate MSI-style log: /log install.log |
| Prerequisite check | Always reinstalls VC11 | Check registry HKLM\SOFTWARE\Microsoft\VisualStudio\11.0\VC\Runtimes\x64 |
| Error handling | Exit with generic code | Return meaningful exit codes (0=success, 1=missing prereq, 2=reboot required, 3=unknown error) |
| Reboot management | Forces reboot without warning | Use /noreboot and detect pending reboot |
| Path flexibility | Hardcoded C:\Program Files\dsyadm | Use %PROGRAMFILES% or allow custom path via /D=C:\custom |
| Integrity check | None | Include authenticode signature and hash verification |
