Hi I have Acronis True Image Home 2009, build 9611 updated to build 9770 It was installed on a PC running Windows XP Home SP3. It worked fine and I had no cause to complain. I have now tried to mount it on a Sony Vaio, running Vista Home Premium SP2. It loads o/k and I can open it with no trouble. However, when I try to open the Browser it hangs and with successive tries at opening the browser my machine runs slower and slower, to the point where my PC is unuseable. If I either delete Acronis, or, system restore to before installing it my machine again run correctly. If I try the install on an Acer Ispire laptop with the same operating system the same senario happens. I have tried running Acronis without the update with no avail. Hoever loading Acronis in trial mode, pre-update version, and then entering the product code, hey presto it works. I haven`t tried to update it in case things go wrong again. Can anyone shed any light or is this version of the software not Vista compatible? Thanks.
