Maybe and maybe not. That's not much to go on, really. If they are telling you that you HAVE to install the program to print some kind of coupon, then I would be suspicious, since you really don't need to.
I've seen one out there that claims it is the only way to make a machine-readable bar code, but that is a lie. I print out machine-readable barcodes all day long from Word, of all things, LOL!
Someone sent me a coupon printer exe file one time and I decided to run it on one of my Virtual Machines, and when I went to install it, it told me that it does not allow itself to be installed on a virtual machine. HUGE red flag!!! About the ONLY things that do checks for VM before installing are malware apps...
Personally, the last time I ran into this, I sent an email to the company and told them that I refuse to install any untrusted 3rd party program on my machine just to print a coupon. The coupon was for $1.00 off their product. A week letter I got a letter of apology from the company, indicating they have received many complaints about that and apologize for any inconvenience, are looking into it, blah blah blah, AND they included a nice shiny FREE coupon for their product! :)
So instead of saving a dollar and doing who knows what to my machine, I wound up saving almost 9 dollars by getting the item for free :) That's my advice!
