Why is mreport.dll giving me errors?
System process errors are mainly due to problems with conflicting applications running on your PC. Consider uninstalling any applications you are not using or use SpeedUpMyPC to selectively disable or remove unnecessary background and auto-start processes. The safest way to stop these errors is to uninstall the application and run a registry scan to remove any residue or corrupt entries.
- there are very few "hits" about it other than about what is it.
There is no info about it on the ICQ web site in it's knowledge base
Your problem may be due to you NOT disabling resident modules of anti-malware software from running BEFORE you installed the software.
NOTE that sometimes the resident module(s) of anti-malware programs - a part that runs all the time scanning for suspicious activity - will interfere with the proper installation of third party software, the software will not install properly, and you may get no indication of that at all while installing the software.
To avoid that possibilty, you should always DISABLE the resident module(s) of anti-malware programs, BEFORE you install third party software (software other than most Microsoft Updates, etc., that did not come with Windows ), especially when it's a major or complicated software package.
E.g. if you are using the free or paid version of AVG, you should disable the Resident Shield in AVG's 's settings in Windows. In Norton (Symantec) products, there may be several things you need to disable, or set so they don't load for a specific short amount of time.
If you don't know how to do that, tell us which anti-malware software you are using.
When you are sure the software has installed correctly, re-enable the resident module(s).
Or, similarly, if you are using a third party software firewall, it may have a resident module that needs to be disabled BEFORE you install software to prevent it from interfering with the software installing properly.
"....and I cannot sign in the old version...."
What is the problem with that ?
Are you using a third party software firewall ?
I'm behind a firewall. What should I do?
