Getting "Source file not found"

Back in November of 2015, I was able to install LoadRunner 12.50 with no issues.  Now, I am getting the following:

Source file not found:

%sourcefolder%\lrunner\MSI\HP\LoadRunner\AppServer\webapps\site.war\images\treeicons\color\RecycleBinEmpty.gif.tmp.  Verify that the file exists and that you can access it.

I have replaced the entire color folder but still get the error.

Any ideas as to what may resolve this issue?
