I just updated to v 4.0.8667 from v 4.0.8604 (64bit versions)
Now I am getting a error message on my Command Line Argument /instance 2 ( or any number)
THE PARAMETER IS INCORRECT

Also. I just tried with v 4.0.8709.0 This also failed to run with the instance parameter set
Is there a new format?
thanks

Hi,

no, no change, and it seems to work fine for me in recent versions.

In the command line, the command should be something like
The 'target' for a shortcut should be basically the same. Notice that the path to SharpCap.exe is inside double quotes, but the '/instance N' bit is outside them. I suspect that somehow you have the format of the command line / shortcut mixed up, since the 'Parameter is Incorrect' message is not a message that SharpCap itself can produce - I expect it is coming from Windows.

cheers,

hi Robin
Not sure what is happening.

Here is the properties shortcut I am trying to use in my Win 11 laptop which is not working

""C:\Program Files\SharpCap 4.0 (64 bit)\"/instance 2"

Here is the properties shortcut I am using in my Win 10 laptop which is working

""C:\Program Files\SharpCap 4.0 (64 bit)\"/instance 3"

I even copied the shortcut text from my win 10 to the 1in 11 system. it does not work.

UPDATE::::
I just uninstalled the newer version of sharpcap and installed v4.0.8604
The shortcuts now work OK.

thanks for looking at this.

Another update.

Just to make sure of the issue. In case it was related to win 11.
I just updated my win 10 laptop sharpcap from v 4.0.8604 to 4.0.8709
I now have the same problem.
PROBLEM WITH SHORTCUT
THE PARAMETER IS INCORRECT
If I leave the parameter off, sharpcap runs ok.
If I revert back to 4.0.8604, sharpcap starts ok with the parameter

wanted to let you.
Take care

Hi Steve,

I still can't make this happen - tried making a new shortcut then upgrading SharpCap and it all works fine for me (exactly the same upgrade - 8667 to 8709). Even if I then uninstall SharpCap I can't get the 'parameter is incorrect' error - I get a more specific error telling me the target is missing.

I'm fairly sure it's some Windows weirdness, but I can't work out what. Does it work OK if you create a new shortcut after the upgrade?

cheers,

Robin

OK
I created a new shortcut after installing the 8709 version.
Where should I try to add the instance command
in the START IN
or TARGET
If I try to modify the new shortcut it will not allow me to add the instance modifier.

here is what the shortcut looks like from the old version and the new version ALSO:
I have noticed even if I setup the instance modifier with the older version of sharpcap
When I create the 2nd or 3rd or more instance modified shortcut, the hardware settings for telescope and focuser are not saved.
it only remembers the last hardware settings i created across all shortcut instances.
I do make sure to APPLY in the properties window when I change the instance.

I must be doing something wrong.
thanks for any help.

RESOLVED.....

OK
with 8709 loaded on the laptop.
I created a new shortcut for sharpcap
Copied it
opened properties of the shortcut
hand typed in the TARGET path
Sharpcap.exe /instance 2
when I hit APPLY
windows showed in TARGET
"C:\Program Files\SharpCap 4.0 (64 bit)\SharpCap.exe" /instance 2

This shortcut now works
The Hardware settings in Sharpcap are also saving properly.. !!!!!!!!!!!!
So, all is working.

I just have to be careful how I create / edit the shortcut.
Sorry about this.
Take care
