I have made sure that Secondary Logon service thing is enabled; I've got the latest version of the Agent folder, it downloaded it itself. There should be no issue with "not an administrator account", and this isn't Vista or Win7. I _have_ got past "Updating setup files", and did get the beta downloaded, installed, and played the heck out of while it lasted. Unchecking "detect LAN settings automatically" in Internet Options/Connections isn't helping, as it's not -downloading- anything yet. I did predownload as far as I can TELL... and there's 7.56Gb of MPQs in that MPQs folder.
In the folder I told it to install in, it did make a lot of .temp files, and has now deleted all of them leaving a Data_D3 folder containing PC containing MPQs containing several .mpq files ... and there goes the Below Minimum Specifications small screen for the third time ... but it doesn't seem to be DOING anything else in between occasionally telling me again I'm somewhat below the minimum processor specs.
Is this a case of "wait for 30 minutes for it to finish making up its mind about what it wants to do, then it will suddenly start the Installing... progress bar across"? If so, you might warn people about that ahead of time. (If not 30 minutes, is there an amount of time I _should_ be waiting before complaining?) The "Downloader Preferences' under Options (and actually four out of the five lines there) is also greyed out.
