Important Note: DocuCom has been discontinued in 2009 and is known to have incompatibility issues when running on Windows 7 or above. If the solution doesn't help, please consider upgrading to Gaaiho PDF because there will no longer be any DocuCom update release.
There are two possibilities:
- 10% chance: The product you are attempting to install does not match the product type registered with the serial number.
- 90% chance: The data is not properly replaced and the activation system incorrectly believes that the wrong product is installed.
Re-installation will replace the old incorrect data.
1. Deactivate DocuCom (skip if it's not yet activated or the option is not available)
2. Uninstall DocuCom
If you cannot uninstall DocuCom via normal procedure (Control Panel > Programs > Uninstall a Program, and find "DocuCom PDF Gold". Click "Uninstall" and proceed), please use the attached Remove Tool (replacing step 2).
