Since v.7.2.42 I am not able to update to newer version. That is a long time now. I am still using this old version:



I get the message there is a newer version available, I download it, start the installation, but the installation always gets stranded here:



The instruction on 0x5bc46935 refers to memory at 0x013fde20. The read or write operation on the memory failed.

This computer still runs on Windows-XP SP3 32bit.

What to do?

Doing a search on the Dutch error, I found a thread filled with Belgians with the same problem, and here it was - at the time - the Kaspersky anti-virus/firewall software that caused the error. Anti-virus software does make sense because it will scan every executable at the time it's started.

So the question here is, do you have anti-virus installed and from whom, which version?
What happens when you temporarily disable the AV before trying to install a newer BOINC?

Nope. Deactivating the antivirus did not help. Still the same problem occurs.

Will I have to remove Boinc completely from my computer?

Than I'll probably will have to start looking for my account information for the reinstall?

What if I lost this information after my previous computer crash?


Real picture of my screen some time ago. A bit later, it did not startup again at all.

If 7.2.42 is working correctly you don't have to update.

The blue screen points to Avira. Note that Avira has not supported XP since April 2016.
