Issue
License Administrator fails install with an "Uninstall failed, installer cannot continue" error
Product Line
EcoStruxure Building Operation
Environment
Building Operation License Administrator
Cause
Building Operation uses Flexera (Revenera) Software Technology for licensing. Other Schneider-Electric products may also use this technology for their licensing.
Resolution
Check to see if the site has other software programs/products using the Flexera (Revenera) Software Technology. Other Schneider Electric offers such as Unity Pro - IEC Programming Software for Modicon PAC, Power Monitoring Expert & TAC Vista as well as third party programs also use Flexera (Revenera) for their licensing.
During installation of the Building Operation License Administrator the dialog below is shown:
The default behavior of the Building Operation License Administrator installation program is to install both Building Operation License Administrator and a new local license server instance. If the default behavior is accepted, the installation program will attempt to uninstall any previously installed local license servers.
If the Building Operation License Administrator installation program does not have sufficient access rights to uninstall the license server previously installed by another product a "Failed to install Building Operation License Administrator" error will occur.
Multiple products can share a single Flexnet License server instance. If there is an existing Flexnet install then the License Server checkbox should be unchecked during installation of the Building Operation License Administrator
This leaves the existing local license server installed by the other product intact, while still allowing Building Operation License Administrator to run. The license server used by Building Operation License Administrator can easily be changed by the user on the License Server Address tab in Building Operation License Administrator, if necessary.
