Things like requesting calibrations to download, VIN rpos ect ect. All things their software does.

Its like anything. Its not a problem until its a problem. But i'd suggest not talking about it too much here.

There are not enough swear words in the world to describe the abuse I just had at GMs techline this morning.

Needed a calibration on a GMC Sierra.. techline starts updating then randomly crashes. Now when it starts, it will not boot correctly, just says reboot computer as a problem has occured.
Snooping further and looking at the logs, techline is preventing starting as its partially written a corrupted version number (Assuming to register) so now things Im running versions of other tools it was trying to install that are incompatible!!!

Should be easy fix right? Uninstall and reinstall? Nope.. why the fuck would they make it that simple. It does not appear to overwrite version numbers if they are higher then whats being replaced with.
Tested on a laptop, which boots and runs successfully with techline.

Now the main PC is unable to actually use techline till I can figure out where all these damn versions are being stored. Assuming I figure it out, Ill post a fix.

*Edit
Its lost the "TDM Service" exe, its no longer installed at all but I believe registry and also the taskmanager services show its on the computer, but cannot run as it does not exist. I have copied it across from the laptop, then used the proper uninstall from control panel to remove it entire... so lets see if it installs correctly now.

*Edit 2
Ok, after doing the above, then going through the registry, and removing everything related to GM/Techline under:
HKEY_LOCAL_MACHINE->Software->WOW6432NODE->General Motors + GM + TDM + Techlineconect + TUM

As well as removing everything in:
HKEY_CURRENT_USER->SOFTWARE->GM+TechLine

It seems to now finally at least be trying to boot up. Its doing a shitload of updates (Again) but at least its progressed from doing nothing.

There is no way in hell any GM tech/help would have resolved the above. It required actually ripping files from a running computer to allow successful uninstall and hand editing registry to get to this point. Looking through the install files under the appdata/local area shows a few powershell scripts which are used during install/setup of techline, although none of them help this situation.

4.5hours later... and we are back in.
What... a... fucking... joke.

If any GM techline engineer is reading this, or better yet, the techline project co-ordinator... splitting up your services into multiple applications relying on socket connections is a terrible idea. You have zero implementation to deal with missing services which could be removed by antivirus or uninstalled. Along with, the timeout values you set when initially setting up the SPS client session are NOT high enough thus clients on mobile signals can time out. Further more, instead of relying on registry version control, use the ACTUAL applications version saved within the program.

Whats even more stupid, logs indicate if something is missing or version is incorrect, the application MUST be a mismatched client program and it just completely stops working. That would have been nice to have an ERROR MESSAGE indicating this instead of having to back trace every single application TLC was checking against.

WOW if that happened to me or most common mechanical service users they'd be royally screwed... good to know how to fix it but it's not going to pay for your time wasted!

FFS...

OY

At least its a solution to resolve. Id hate for a mobile program guy to have travelled hours and be stuck because of some bullshit like this. Hopefully does come handy to someone searching.

Hi all;

THIS is why I used to keep a backup image of my PC when I was doing work and I could NOT afford to be without my PC (Used Norton Ghost to create an image of my Windows XP HDD)
NOW, I don't really keep anything important enough to lose this way. (Wiping and reinstalling the OS is time consuming but not impossible)

It was a giant clusterfuck for all gm dealers.. They pushed the update thru sunday at 10:57pm, evidently they had the janitor hit the 'update' button before he went home and nobody checked the fucking thing to see if it was any good.. First thing monday morning turned into a shit show with nobody being able to do a god damn thing.. Everyone that needed gds2 or sps was basically fucked.. Some emails went out, some numbers were called and GM was finally woken up out of their holiday day off and had an emergency meeting where they pulled the update and went to backups around 8:45EST.. if you tried to use it before then you were screwed but since they pulled the server you could download the tlc install program and run it and it somehow straightened itself out.. email below came out around shortly after 11am..
