Could I know how to get over the error encountered during the installation of plugin.

Failed to download and install microsoft script debugger , ''with .exe path'' . Please check log file for more information.

How do I get over this error.

Yes, depending on whether or not the machine has UFT installed:

a) If the machine has UFT installed, the UFT Plug-in for ALM is installed via a Change on the UFT installation (or selected during a first-time install of UFT):

Windows > Control Panel > Select 'HP Unified Functional Testing' > Change > Next > Change > **Make sure 'ALM Plugin' Will be installed on local hard drive** > Next > Change

b) If the machine does NOT have UFT installed (e.g., the user just wants to view UFT test scripts in ALM Test Plan without installing UFT on the machine), the UFT Add-in for ALM can be found in the ALM Tools page. Here's a direct link:
