G-Series Gaming Keyboards

Mine finally is working.  I got a new computer and fresh installed everything.  Started working with the newer version of the Gaming software.  Obviously, not a cost effective fix, but it shows that it's not hardware related.  Has something to do with the drivers.  Good luck to everyone with the problem.  Hopefully Logitech will address this issue since a lot of people seem to have it.

I haven't read the whole post but I had the same problem. I solved it by installing the 1.04 drivers first, then the game panel software, then the latest 7..... what-ever driver, that is avalible now.  Works a dream now.

DON'T UNINSTALL, JUST UPDATE THE PREVIOUS DRIVER INSTALL!!!!!!!!!!!!!!!!!!!

Hope that helped you

So I've gone ahead and figured out what the problem with the runtime error is. It seem that logitech isn't having lcore.exe aquire admin rights and as such is being denied access to the  C++ runtimes it is calling on.  Some people figured out that if you just let the lcore.exe crash at startup and then lanched it by right clicking and running as admin it would work. 

Before that, my specs are:

AMD Phenom II x4 965 3.4ghz

ATI 6970 2gig Refrence Card

Logitech G35

Logitech G19

The point of this is to show that I am using ALL of the hardware that has been assused of being at fault for the errors and yet the fix below works without installing or uninstalling anything.  

The fix for this is sickeningly simple but understand that it will leave your computer less secure then Microsoft would like.  No less secure the Windows XP before SP1 mind you, but still less secure. 

1) Open Control Panel

2) Open "Action Center" or click on "Review your computer's status" under "System and Security"

3) Near the top left of the screen click "Change User Account Control settings". (The one with the shield)

4) Slide the bar all the way to the bottom and click OK.

5) Reboot.

The lcore.exe will launch just fine at restart. No more runtime errors.  

I have tested this multiple times by sliding the security setting up one notch and rebooting....error.  Down to bottom.....fine.   I also have another system that has the same hardware except for a G510 instead of the G19 (the wife liked having more macro keys). Same thing happens on her system.

Anyway enjoy your hardware!

I was able to fix my problem which was due to I beleive the installing of the older software and it didnt completely uninstall. I uninstalled  my all my logitech software. Then I searched for logitech on my C: drive which was which had the installed software originally and found some folders that where left over and deleted them. Also I deleted the Logitech information in the registry at HKEY_CURRENT_USER\Software\Logitech and HKEY_LOCAL_MACHINE\SOFTWARE\Logitech. Then reinstall software and all is working. Hope this helps.

For what it's worth, I started getting this error today after replacing my single GPU 465 with a Multi-GPU 590, which is really odd if it's a simple security issue (though running as admin does clear it up).

I _think_ that as long as I was in SLI mode, it worked, but when I turned off SLI to hook up 3 monitors, it failed.  I can't say for certain, though, because I later put my 465 back in so I could have both 3 monitors and SLI (and it fails again).

YES!!!! Finally fixed it.

Out of nowhere I started having this issue TODAY!!!! With the latest LGS (tried all versions from 8.0 onwards).

Nothing, absolutely nothing worked. My only option was re-installing 3.06.

So I tried re-installing the runtime libraries c++ 2005/2008 nothing worked. But I noticed that everytime I tried to start LCore.exe (even using elevated privileges) was eating 1.3/2.0gb of RAM until finally crashed with the Runtime Error, every single time.

So I started looking around and..... to my surprise I've found json configuration file with a similar size: HERE ---> C:\Users\XXXXXX\AppData\Local\Logitech\Logitech Gaming Software\settings.json

I immediately deleted the g'dam file and IT WORKED!

Seems like at some point my configuration file got corrupted (I think) and when the software tried to read it, it crashed.

Give it a shot guys.

OMG Thank you NamelessOne! it finally works for my 8.20 version!

[figureouturself]

I've got the same problem. Trying to get it to work for my G15v2.

I just re-installed Windows 7 x64.

Disabled UAC. Installed lgs8.2 and it comes up with the runtime error.

Run as Admin does the same thing.

Tried deleting the settings.json, no dice.

Installed lgps3.06, that worked, installed lgs8.2 over it, runtime error.

I went to MS download center, downloaded and installed vcredist for 2005sp1, 2008sp1 and 2010 x86 and x64 versions, thats 6 vcredists. Still get the runtime error.

Anyone have any other solutions?
