WampServer

I know it's WAMP forum, but my problem is partially related to WAMP (or at least Apache) and I am looking for the answer everywhere.

I have an annoying problem. I have application deployed by clickonce (made in .NET). Until now it was working really well and a lot of updates were deployed easilly. This time I had to do some major changes in my app. That causes update is about 16MB. Unfortunately most of time on clients computers error occurs during downloading update (in random moment):


ERROR SUMMARY
Below is a summary of the errors, details of these errors are listed later in the log.

Ofcourse I replaced real IP by Xs.
Only once it updated properly. I use WAMP as the HTTP server.
I've been Googling it for some time, but haven't found anything usefull acutally.

Thanks
