latest version won't install in WinXP, earlier versions flagged by virustotal

[jbclem]

When I try to install latest Firemin in WinXP I get this error:
"F:\Firemin\Firemin_5338_Setup.exe is not a valid Win32 application", so I'm assuming it's not meant for Windows XP. This latest version pased VIrustotal.com with no flags.

I found some earlier versions to try, v6.x and v4.x but when I ran them through Virustotal.com they were flagged by five out of 61 engines. They came from FileHippo. I also ran Malwarebytes 1.7 on the partition where these Firemin files were stored and it didn't flag any of them. So does this mean anything? Here are the five flags:

Comodo ApplicUnwnt@#gz16caeznb2a
Elastic Malicious (high Confidence)
ESET-NOD32 A Variant Of Win64/InstBase.B Potentially Unwanted
Fortinet Riskware/InstBase
Malwarebytes Trojan.Crypt.MSIL

Is there a way to install the latest version in WindowsXP.?
