FenestraPro identifies previous versions of the application and will manage the database files which are stored on your machine (previous Solar Load Calculations, Custom Groups and Codes, and Log files etc). Once installed, FenestraPro will rename older folders and save this data.
If an error message appears, try clearing the cache files in the FenestraPro folder. This folder contains previous data and calculations from projects which have been analysed. If the project has been modified or was previously viewed in a different version of FenestraPro, this database may need to be deleted to start afresh.
The folder may be found in this location on your machine:
C:Users\< User Name>\AppData\Local\FenestraPro.
All the files may be deleted here (previous results and setting will be lost however). New files will be created when FenestraPro is opened again in Revit.
User Permissions / Firewall & Antivirus
You may also see an error message when you launch the application if you do not have user permissions to access certain folders (to create the license file) or if the web service connection that FenestraPro uses is being blocked by your firewall/antivirus protection. It may be necessary to get advice from your IT Department for these issues. Please contact us for advice first (support@fenestrapro.com) on instructions for testing our endpoint if required. It is also helpful for us if you can expand the error message fully to view the full message and email a screenshot to us for advice.
