Hi there Calvin S Cole

When we did not install Lync 2010 client by using client executable file this problem will occur. So in order to avoid this follow the steps shown below

Step 1 – Go to start > Run > type regedit and hit enter

Step 2 – Locate this path


Step 3 – Go to edit > New > Select DWORD Value

Step 4 – Type this UseMSIForLyncInstallation and hit enter

Step 5 – Give 1 for the value data then press ok

Step 6 – Exit Regedit editor

Step 7 – Restart windows client

Best of luck
