Well, I have in computers I use with Windows XP or Seven more than one browser installed on them, generally Internet Explorer 8, Firefox 4, Opera 11 and Google Chrome.

I often use Firefox, but I want to use Google Chrome sometimes because I have a lot of addons and webapps on it.

The issue is: when I try to execute Chrome after some months without using it, it does not function. Using Proccess Explorer or Task Manager, I can see that there is not any Google proccesses running. Then I reinstall it and all functions. But if I do not use it for some months again, it will not function...

Is it an update problem? Must I use Chrome everyday or is there another way to avoid that issue?

PS: I installed English and Portuguese last versions (how to get the version numbers when it does not execute?), not at the same time, and it continues to do not launch...

PS2: There is a running Google Update proccess that is launched in startup:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
   Name:            Google Update
   Type:            REG_SZ
   Data:            "C:\Users\Ubirajara\AppData\Local\Google\Update\GoogleUpdate.exe" /c

Probably - if a reinstall solves the problem. You could just open up Chrome once a week to let it auto-update. – ChrisF Apr 4 '11 at 21:09
    
Well, I think the cause would be it, but I'm not sure. I googled it but did not found anything about. I can test using Chrome one a week :) but I would like to know the cause and the best solution. ChrisF, do you know a way to program Chrome autoupdate (settings/command line for batch or shortcut/scheduling in Windows)? – kokbira Apr 6 '11 at 14:31
    
Sorry, no. There is the Google Updater tool - do you have that running? – ChrisF Apr 6 '11 at 14:32
    
Using Autoruns I can see some Google application that is launched with Windows startup... Later when I arrive home I can write its name. – kokbira Apr 6 '11 at 18:58

If you have not deselected the options to back up your data -- on by default when you sign into Chrome with your Google account -- you can (uninstall and) reinstall Chrome. Your synced settings will be restored when you log in to the fresh Chrome.

Sorry, I didn't see that you already tried that. This seems like the simplest route -- Chrome is built to be refreshed from a server, and will even install to a non system location by default, allowing it to be a transient, up-to-date application with data "in the cloud." I can't think of one reason why you would need to run the outdated version. – maxwellb Jul 16 '13 at 3:26

Are you running a third-party software firewalls of any kind? If so, are they configured to silently block executables that have changed (i.e. due to upgrade)?

Surely these would either complain or block the reinstalled Chrome too. – ChrisF Apr 5 '11 at 22:24

It might be Chrome has some security feature that prevents it from starting if it's too out-dated. That would sorta make sense, because badly outdated browser is a big security risk. However, it should autoupdate itself, not just refuse to start....
