If you go to your Account / Product History / iC5 / Bonus & Upgrade, you'll see there are 3 Downloads:
1) Current Version
2) iC5.2 Patch
3) iC5.2.1 Patch
IMO, you need to Install all 3 in consecutive order.
However, if you look at my Screenshot, you'll see that the Current Version (Update) Date is the same as the separate 5.2 Patch Update date. Therefore the current Version might also include the 5.2 Update. If-so, why iclude the separate 5.2 Update Patch? Illogical
That being said, I have several e-mail exchanges with Technical support re; unable to Download Market Place Inventory items.
I've spent a week trying to resolve it my end. I can't fathom-out Reallusion's Program & Updates Logic, which isn't the way all of the other Programs I have re; Program delivery & Updates, which are industry standards.
BTW - There's a correlation between Program Version Numbers & MSI Installshield Corporation Version Numbers.

I deleted my previous download of ic5 pro and re-downloaded and installed it.
I checked the version, it tells me I have 5.2.1618.1, on your web page that
checks the installed version, it tells me that I have 5.2.1618.1 installed.
http://www.reallusion.com/iclone/iclone_upgrade.aspx
The above page says that 5.21.1627.1 is the Official Release Version.
Now I just got done d/l and re-installed ic5 only. I checked the version
in the help about tab. It says I have 5.2.1618.1 loaded. I am courious
why I wouldn't have gotten the 5.21.1627.1 version.
And I tried to re-install the newly re-downloaded Physics Toolbox,
No Luck, the same error that Username and Password
dont match my account info.
