Cause

The Laserfiche Server installation package does not correctly differentiate between .NET Framework 1.1 and .NET Framework 2.0. The Laserfiche Server installation cannot proceed if you only have .NET Framework 1.1 installed.

Resolution

Perform one of the following:

  • The Laserfiche Client 8.0 installation includes .NET Framework 2.0. You can first install the Laserfiche Client on the computer where you wish to install the Laserfiche Server. Then run the Laserfiche Server installation.
  • Visit Microsoft's online resources and manually download and install .NET Framework 2.0.
