Installation of "VAC" in Windows -10

Earl

     I have been unable to install  "VAC"  (Eugene Muzzychenko) software in my new computer running Win-10 OS.  I have used up all my "paid for"  4 downloads trying (ouch!).  How does one get this software to load (or to disable the "digital signature requirement" of Win - 10 - if this is necessary)?  I need to know before spending more bucks trying!
    Is there an alternative software available?  My FLEX Smart SDR & FLdigi installed and running properly - I'm otherwise ready to go!    HELP PSE!
Tnx,
Earl - N1VP

Are you using SSDR?  If so, you do not need VAC.  When installing SSDR it should also install DAX which provides basically the same thing VAC provides.

Send an e-mail to Eugene asking for support.

If you haven't already tried it, try at boot up go into unsigned driver setup (see step by step using google getting into unsigned driver mode) and try to load VAC. 
I had to do this with SmartSDR CAT and DAX drivers to get them to work properly on my WIN10 upgraded computer. 
Hope this helps and 73's

What error are you getting? What problem are you seeing? Can you describe the specific symptoms you're seeing? Ultimately, the driver's author IS the one who provides ultimate support, but we'll try to help you here if you describe what you're seeing. Peter K1PGV

I had the same issue with win7 and the vac driver I had to run win 7 in test mode to load it (VAC driver). However, vac is ONLY needed for powersdr. I am, not at all, disagreeing with what Peter just said, but if it worked on win7 and doesn't on Win10, why not just bag Win10? The fact I had to run Win7 in test mode because the author of the driver couldn't sign it made me not want to use psdr, or win 7.

I tried that but he didn't respond!

My VAC installation survived the upgrade to Win10. Is 32bit version.

Seconding Don's comments - if you're using SmartSDR, use the DAX product, not VAC. It works better, is supported by Flex, and doesn't require you to do too much configuring.

Mine survived upgrade to WINDOWS 10, 64-bit from WINDOWS 7.

 I have it working now -  the secret was in learning how to disable the "digitally signed  driver requirement for unsigned drivers" ("VAC" is not a digitally signed driver).  Installation was then straight forward and I am now up and running (using FLdigi and Flex PowerSDR 2.7).  It also helps to read user guides supplied with software - shame on me).
Thanks to all who responded to my cry for "HELP!"   - your help was appreciated!

Earl,

I'm glad you got it working... but as far as I can tell, you shouldn't have to disable driver signing... should you?

I looked at the V4.14 file that's installed and the driver itself IS indeed signed correctly.

If you're good with what you're doing now, that's fine... I don't mean to make more work for you.  But I seem to remember VAC being a properly signed driver (though it is not properly installed via a signed driver package), and looking at it just a few moments ago it still looks that way.

Hey Peter, if it isn't too involved would you mind explaining how to get it properly installed maintaining 'prod' mode? Subsequent to the arrival of the 6500 I uninstalled the VAC driver and placed Win 7 back in Prod mode. That pretty much means I can't use the 1500 any longer. So I suspect additionally Earl would benefit from knowing how to install it properly.

Thanks,

Walt

I'm not sure how the author instructs folks to install this driver.  Does he specifically say to bypass signing?

There are two parts to kernel-mode code signing:

1) Signing the install package

2) Signing the driver executable image

The driver itself certainly looks like it's signed so that it will load (see below)... but it also looks like he hasn't created a signed driver package (which would entail having a .INF and a .CAT file)... is that right?  Because I don't SEE this package in his ZIP archive (and I'd rather not try to run his setup program on my development machine).

The one interesting thing is the code signing certificate he's using expired in 2011... and he apparently signed the driver in 2010.  If his code signing certificate is no longer valid, that would explain why he hasn't/can't create a proper installation package for his driver that'd allow it to be installed with "normal means."

When I installed VAC "back in the day" I don't remember having to bypass driver signing.  But that was a long time ago, and I might have installed in on an x86 machine (where there IS No driver signing requirement).

I know, that's a relatively long but not a very helpful answer...

Thanks Peter. If I understand you correctly, the only way I could reinstall that on win7 is to force win7 back to test mode. That struck me as strange at the time in that it not only didn't put just the driver in test mode it put the entire OS in test mode. Perhaps that was not necessary but that's the only thing I could find on Google. Further sounds like what you're implying is rather than put the entire OS and test mode one could put it in a mode such that it would allow unsigned drivers which seems less severe than test mode. What was interesting is once in test mode down at the bottom right of the screen there it was in and white lettering TEST.
