I'm trying to install iTunes 12.5.5 32 bit using Wine on Ubuntu 16.04. I kept getting a message saying wine couldn't find C:\\windows\\system32\\iTunesSetup.exe, so I moved iTunesSetup.exe into the C:\\windows\\system32 directory. When I tried to install iTunes again, I got:
tom@M645:/$ wine iTunesSetup.exe
fixme:advapi:EventRegister {5eec90ab-c022-44b2-a5dd-fd716a222a15}, 0x401123, 0x41e030, 0x41e048

Using single-platform PRODUCTCODE.

Product to install: {B7C4ABF3-59A7-47AB-A72E-956BA5B4841C}

FDIIsCabinet() failed: 'C:\windows\system32\iTunesSetup.exe' is not a cabinet

Returning: 0
I'm new enough to Linux that I don't know what to do next. Any ideas?

Thanks in advance,
Tom
