Thank You @L.Maas!!!
I have written the answers for your queries.
-When is this error popping up (e.g. during saving, opening projects, starting Revit)
During saving the projects and families.
-Which Revit version?
With all versions of Revit (Arch, MEP)
-Latest updates installed (i.e. Revit, windows)?
Installed UR 3 for 2014 versions, and no UR for 2015, 2016 versions,
-Does this happen with all projects?
Yes,
-Is this relating to central file?
For local as well as central files, But this time I'm asking for local files.
-Where is the central file placed (e.g. local, network)?
Always in network,
-Add ins used?
COINS section box (Downloaded from Autodesk app)
Also we installed one addin to switch the point-cloud on and off (customized in our Organization and all are installed this, but no one face any problem except me),
-Only issues with Revit or also other programs
Only with Revit,
**Some possible causes.
-Slow Network
-Permissions (write) to access folder where project is located
-Third party apps/add-ins
-Virus Scanner or Firewall**
Just want to let you know: If these are the problems to cause the error, why I only need to face this? While all are installed the same addins/third party apps.
I have not problems with Permissions (write) to access folder where project is located. Kindly get me out from this error. Thanks for your time to taking care on this.
