Hello. Just upgraded from v9 to v10 (and moved to a dedicated 3CX server – 2008 R2) and am having this consistent issue putting MyPhone on first desktop (my Vista laptop): Run the exe. First error is that there is not enough disc space to uncompress and install prerequisite software (not true). Second error is that .NET4 prerequisite was not correctly installed 4154. But I have .NET4 in and up-to-date. But given issue 1 I could accept. Third error is I don’t have sufficient privileges, so log on as Administrator (again, not true – I am Administrator of this computer). Any ideas gratefully received. Thank you.
