Unchecking the attribute "For fast searching, allow Indexing Service to
index this folder", for the GPL installation will cause GPL to crash to
desktop.
However, I will also have to add that this action doesn't index the files.
To have the files indexed, you will also have to have the indexing service
running, and the path in an index.
The indexing service can be found in Control Panel/Administrative
Tools/Services
You can also set it from the search tool.
And finally you can set it from the Computer Management/Services and
Applications/Indexing Service.
If you stop the service, no index will be created or used.
Also if you look in the Catalogs in the Computer Management/Services and
Applications/Indexing Service, you can include or exclude directories from
the index.
I've looked into the GPL exe, and it seems it uses the FindFirstFile API,
and there are reports that the API may be using the indexing service "under
the hood". It hasn't done that before, and it seems rather ill documented.
Here is a link to a google-search if someone want's to dig more.

Conclusion;
Indexing is not necessary.
Removing the allow-indexing attribute on the files will cause GPL to fail.
I'm sorry for my stubborness on this matter, but I thought you were saying
that the Indexing is vital to GPL.
