Can't open either Jschem or ExpressSch files?
« on: January 27, 2013, 07:23:33 am »
I really would like to open these newer type files I see on the forum and I downloaded both programs onto my PC laptop. However, they still won't open and the Windows 7 'trouble shooter' program keeps sending me to these add on 'Registry' file cleanup programs that want 30 dollars to clean up my one laptop and supposedly make it open these files. Can anyone please walk me through getting this problem resolved?

thx, smacko jack

ExpressSch files

1. Locate a *.sch file here on the forum. Save it to your desktop.
2. Double click the file to open it. If windows can't open it you'll have to "select a program from a list of installed programs".
3. ExpressSch probably wont be listed so you'll have to 'Browse" to the folder where it is installed. The path will probably be...

                     "C:\Program Files (x86)\ExpressPCB\ExpressSCH.exe"

4. Be sure to check the box "Always use the selected program to open this kind of file"

After properly associating *.sch files with ExpressSCH.exe, you should be able to open sch files directly from the web thru Internet Explorer.

Now use the same procedure to associate the Jschem files with the Jscheme program.


A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

smackoj,
That could be aTROJAN "Registry Cleaner" that is trying to get your credit card info and then leave you worse off than you already are.

I've seen many of these types of malware,,,and they usually generate a list of files that your computer actually does need, and they list them as harmful files, in an attempt to get you to believe that they are actually doing something to protect you.........they also use a graphic interface that looks very official and believable.

If you have a anti-virus scanner that will run in safe mode, you should do it to remove any trace of that "Registry Cleaner" from your system.....whatever you do, don't buy the service!.....ask for more help if you need it or have a relative who knows computers take a look at it if it's over your head  :icon_biggrin:

If your computer is already infected, Windows Defender makes a new (FREE) bootable scanner that I have found to be helpful.....you load it on a flash drive and then tell your computer to boot from that drive and it starts a scan before anything else can start.....very effective
