need mail icon to start thunderbird (not webpage)

[algernon]

Hello everyone... sorry, but this questions has been asked before. I have looked at probably all the solutions and I am still unable to get it to work.

Before I say anything else: I LOVE Rainmeter!

Here's the issue: I can't get the "gmail" mail icon to bring up thunderbird. No matter what I do, it still brings up my web browser.

I have changed the following files:
1. ReaderGmail.ini
2. Mail-Icon.ini

here's is the whole line that is used. I only modified the path to thunderbird:
LeftMouseUpAction=!Execute ["C:\Program Files (x86)\Lanikai (64-bit)\thunderbird.exe"][!RainmeterHideMeter TitleActive][!RainmeterShowMeter Title][!RainmeterRedraw]

The line is exactly the same in both files (well, the path to the executable is. This is from ReaderGmail.ini, I haven't actually checked the other one).

I'm running a Windows 7 x64 system and my Rainmeter is also x64.

I can't think of anything else, but if you need to know something, just ask.
I appreciate any help.
