I bought an EA and successfully downloaded an activated it on my PC (Windows 7).
Then I was going to do the same on a VPS (Windows Server 2008 R2 Enterprise). Exactly the same procedure. I log in with my MQL5 account so I can see the EA under Market/Purchased. See attached image. It says "Product is purchased, but not downloaded" and a Install button. When I click the button, nothing happens. There are no error messages in Experts tab.
I tried to copy the file to the data folder manually. The text about the product is purchased but not downloaded disappears, but then there is an error "cannot load ....ex4" when I try to open the EA.
It does not help to run MT4 as administrator.
I have no clue why it fails, please help!
I do not remember the limitation for the Market concerning VPS so it may be new limitation.But from what I know -
Support for Windows XP/Windows 2003/Windows Vista to be discontinued after 01 October 2017https://www.mql5.com/en/forum/193992 and more - https://www.mql5.com/en/forum/216552#comment_5833564
some more limitation which may be related to your case (and may be - not):

We are fully focused on the exclusion of the 32 bit versions of MT5 programs:

This has been partly resolved.
I still don't know why it is not possible to install the EA from the Markets tab.
However when I asked the author of the EA to help me it turned out that when I tried to manually copy the EA file I copied it to the wrong directory. I had to select the correct directory from the menu item "Open Data Folder" and place it directly under MQL4/Experts, not MQL4/Experts/Market.
So now it is possible to attach the EA to the chart, but I'm still wondering why it's not possible to install in Markets tab. I have asked the service desk. Maybe the OS is too old or wrong 32/64-bit.
It works just fine on Windows Server 2008 R2. It could just be that your VPS is not properly configured or that some firewall settings are blocking the communications for the download.
Also it may be helpful to check permissions of MQL4/Experts and MQL4/Experts/Market in Windows filesystem.
It's still unclear what did you mean here:
I tried to copy the file to the data folder manually.
What did you do exactly?
If you are on Windows (because Linux and Mac does not work with the Market) - use the following threads/pages for more information:
