Unhappy Tophat2 running test_data Errno 8 failed to Index splices

Hello,
I am running into problems when trying to get Tophat2 set up following this tutorial: https://ccb.jhu.edu/software/tophat/tutorial.shtml
I have Bowtie2, Bowtie2-build, and bowtie2-insect in my path as well as the directory to my tophat2 file.
When I run the command [tophat2 -r 20 test_ref reads_1.fq reads_2.fq]
I get the following message:

[Errno 8] Exec format error

I have seen that others have discovered they have installed the wrong type however I have check and I have installed bowtie2-2.3.3.1-linux-x86_64 and tophat-2.1.1.Linux_x86_64 on my windows system working on a 64 bit PuTTY system.
Sorry for the drawn out question, I'm fairly new to this and wanted to provide as much info as I could.
Thanks in advance for anyone who could help
