To resolve this issue:
- Go to the appropriate directory:
- For SMEX: ..\SMEX\Debug folder
- For WFBS MSA: C:\Program Files\Trend Micro\Messaging Security Agent\Debug folder.
- Search for the SMEX MSI product ID by looking for the SMEX_MsiSetup-*******.ini file.
The MSI Product ID is the alphanumeric number portion of the SMEX_MsiSetup-*******.ini file (SMEX_MsiSetup-<MSI_Product_ID>.ini).
Example: The MSI Product ID in SMEX_MsiSetup-{9CCFC942-0DA3-44DF-8D61-66FD17A773EC}.ini is 9CCFC942-0DA3-44DF-8D61-66FD17A773EC.
The MSI Product ID is different for each environment. - Open the Registry Editor. Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
- Look for the MSI product id in the whole registry and then delete all of them.
- Close the Registry Editor.
- Perform another installation.
Should the issue continue to happen, perform manual uninstallation of the failed installation:
- Ensure that the correct account privileges is being used in the Administrator's account before doing the uninstallation.
- Uninstall ScanMail for Exchange.
- Once the SMEX software is removed, restart the server and then reinstall SMEX software.
