Upgrade and Uninstall Problems
If you have difficulty upgrading to a new version of BridgeComposer, or with uninstalling,
then your current
installation may be damaged.
For example, Windows Installer files pertaining to your current
BridgeComposer installation may have been quarantined by your anti-virus
(due to an erroneous false positive).
If you receive the above message ("The feature you are trying to use is
on a network resource that is unavailable"), it is looking for the installation
package for your current version (5-58 as shown in this example). Note this
version and click "Cancel".
We suggest you proceed as follows:
We recommend that you temporarily disable your anti-virus during all
install, upgrade, uninstall, and repair operations.
- Disable your anti-virus.
- Download the .msi file for your current version (from the
Archive page or using
BCInstaller "BC Website" tab).
- Run this
.msi and you will be asked whether to repair or remove: choose "Repair".
- Retry the upgrade or uninstall.
- Reenable your anti-virus.
