OK, so it seems that I didn\'t understood how to fix the problem. I read the specified thread and there were 2 solutions described:
1. Complicated ... move the boinc data to some path without spaces in it, edit some registries, edit some xmls. ... which I won\'t do.

There is an easier way of doing this:

1. Uninstall BOINC.

2. Move the remaining BOINC folder to, for example, C:\\BOINC.

3. Re-install BOINC to that location.

The problem arises because BOINC tries to start an application but finds something else instead. Another solution therefore is to find what BOINC is trying to start and remove it. This -2/193 problem affects only a small number of BOINC installations: in other words, most BOINC installations work fine even when installed to the default location (which includes spaces). So, the problem is not the spaces in the Windows path, it\'s that something has \"got in the way\". In the case of your machine that \"something\" appeared at about 20 February, so you might be able to remember whether anything was done to the machine at that time.

For example, if the normal BOINC path is C:\\Program Files\\BOINC, then you must not have a file called C:\\Program on your machine, otherwise BOINC will try to start that instead. As I mentioned in my earlier post this may affect other applications as well - it\'s not an intrinsically BOINC problem - though BOINC/CPDN haven\'t worked around the problem as they could have done. Future applications will not have this problem.

It seems I have a problem. Please advise

It seems that your computer has the problem described in this thread: Exit status -2. Last error = 193.

Before approximately 20 February 2010, your machine was running models normally: since that time there has been a problem in which BOINC cannot start properly because of Windows path handling. This problem may be affecting other applications on your computer and not just BOINC (e.g. some services), so it is well worth fixing.

Have a look at that thread and if you need any further advice then post back here. When you post back to say that the problem is fixed then Milo will re-enable the downloading of models to that computer.

Hello, and thank you for the quick answer. I edited my project preferences and selected only the FAMOUS model. I hope the problem is fixed now.

Dear binic:

The FAMOUS model is not presently available. Check the server status page.
