Hi Henk

Thanks for the update.

I'll take a look at how to speed up the shutdown, it should take no more than 15 secs or so to shutdown the G8JCFSDR completely. For example, if U change the sampling rate, the G8JCFSDR will restart, and as part of the restart, the G8JCFSDR waits until the previous instance has completely exited out of memory, so this period is a good measure of the length of the shutdown time.

I use AVAST for Anti-Virus, I wonder if Windows Defender is doing something more than checking if a program is infected when it is started up ?

Hello Peter

i did this without manual changing register and the program still works.

one remark I have that when closing the program it stays very long active in the backgound , first as aplication then as process. Could you have also a look at that. This prevent you from restarting the program quickly after you have closed it. I then also see the antimalware process of windows 10 being active at the same moment.

Thank U Henk for the good news :-)

Could U please uninstall the old 282 version from that other PC, and then re-install with 282.6 and make sure all is OK ?

Really appreciate the report.

Peter

Hello Peter

i have tried the 282-6 installer on another pc that did not have previous installation and it works ok on that Pc

Regards

Henk

Hi Berend

Sounds promising :-)

Could U take a screenshot of the G8JCFSDR with it running please so that I can see your settings ?

Hi All

It's been an intensive few hours here, but I think I may have the proper solution, ie X32 and X64 compatible Build 282 installer.

The release candidate for the latest build 282 installer may be downloaded from

Since there have been several false dawns in producing a fully functional 282 installer, I will not make changes to the website for a few days to enable people to try out the new installer and let me know if there were any problems.

In order to produce this build 282 installer, I had to fire up an XP Virtual Machine transfer all of the G8JCFSDR Build 282 components across and run the InstallShield packager - really tedious, but it seems to have worked.

Thank you all for persevering with me and helping to get build 282 usable across most environments, really appreciate it.

Hi All

After further investigation, it would seem that my version of InstallShield is not 100% compatible with Windows 10 unfortunately and doesn't correctly generate the code to register the DX8VB.DLL at install time :-(

So, I have used one of it's features to run a VBScript at the end of the installation process which carries out the registration - unfortunately this fix does NOT work for Windows 32 bit. For those interested, the script is named RegDX8VB.vbs and can be found in the G8JCFSDR install directory, usually C:\Program Files (x86)\G8JCF\G8JCFSDR, and consists of

Set oShell = CreateObject("WScript.Shell")
oShell.Run "regsvr32.exe /s ""C:\windows\syswow64\dx8vb.dll""", 1, True

I have tested the new installer on a clean environment and it does seem to work correctly now.

For those interested in the low level details, do the following

1) Run CMD.EXE As Administrator
2) reg query HKLM\SOFTWARE\Classes /s /f dx8vb.dll
??? which searchdes the registry for dx8vb.dll? and on my machine generates the following lines

??? HKEY_LOCAL_MACHINE\SOFTWARE\Classes\TypeLib\{E1211242-8E94-11D1-8808-00C04FC2C603}\1.0\0\win32
??? (Default)??? REG_SZ??? C:\windows\SysWow64\dx8vb.dll

?? HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{58356C5D-0BFD-48ED-93C5-F4520B6233DE}\InprocServer32
??? (Default)??? REG_SZ??? C:\windows\SysWow64\dx8vb.dll

?? HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\CLSID\{E7FF1300-96A5-11D3-AC85-00C04FC2C602}\InprocServer32
??? (Default)??? REG_SZ??? C:\windows\SysWow64\dx8vb.dll

?? HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WOW6432Node\TypeLib\{E1211242-8E94-11D1-8808-00C04FC2C603}\1.0\0\win32
??? (Default)??? REG_SZ??? C:\windows\SysWow64\dx8vb.dll

?? End of search: 4 match(es) found.

The important lines are those ending with "\1.0\0\win32". With the previous 282 installers, these lines were never added to the Registry.

When 282 is un-installed, the lines ending "InprocServer32" are removed by the uninstall, but the "\1.0\0\win32" lines are left behind. To absolutely clean your registry of the DX8VB.DLL registrations, one needs to start up regedit and delete the keys ending with "\1.0\0.win32" - not something I would recommend or is neccessary because if you make a mistake you could damage your registry.

Anyway, I really hope the new installer cracks the problem, so please could you install build 282 from and let us all know if it works.

I can confirmn that this new installer doesn't solve the problem either unfortunately.

For now the only fix is to install 282, then manually register dx8vb.dll as follows

Run cmd.exe As Administrator
cd c:\windows\syswow64
regsvr32 dx8vb.dll

Hi Henk

Thank you for the report.

Bad news :-(? Back to the drawing board

Peter

Hello Peter

I also did try to run the installer as administrator before rgeistering the dll manually. This did not help

regards Henk

Hello Peter

ones it was registered manually one time the next time you reinstall 282 after uninstalling it is till registered and 282 will work after installation. Only the first time it has to be done manually.

regards Henk

Hello Peter

the new installer does not solve the problem with registering the dll, i tried it yet on another computer and also there i had to do it manually as above, sorry for this.

regards Henk

Hi All

I have updated the installer for G8JCFSDR Build 282 and made it available on the G8JCFSDR site

I have tested the new installer and it seems to work on my machines, but the real proof that the problem has been solved is for other people to try it out on their machines please, (NB if you need to regress to Build 280, in addition to uninstalling build 282, U will also need to use XLoader to upload the 1.2 firmware after U have installed Build 280).

I would be really appreciative if you could confirm that this new installer works correctly.

Thank You Everybody for all your help in helping me fix this problem (I hope !!), and look forward to feedback

Peter - GM8JCF

Thank Henk for letting me know, I am might relieved !!!

So now U can try out the higher sampling rates and see more spectrum :-)

Thank U for persevering with me to find this problem

Peter - GM8JCf

Hello Peter

that did it ,thanks

regards Henk

Hi Henk

I think I've found the problem. When I installed G8JCFSDR Build 282 onto a clean W10 machine, I got the exact same results as you've seen, ie no spectrum although everything looks correct.

The problem I discovered is that DX8VB.DLL wasn't registered by the G8JCFSDR 282 installer program, quite why I have yet to investigate.

To fix this problem until I fix the 282 installer, please try the following.

0) Install build 282 using the 282 setup installer
1) Start cmd.exe As Administrator
2) cd C:\Windows\SysWOW64
3) regsvr32 DX8VB.DLL
?????? Windows should respond that the DLL has been successfully registered
4) Startup G8JCFSDR and all should work !!!

Hopefully this is it, please let me know how it goes !

Hi Henk

Ah, yes, my partner got a brand new W10 machine for Christmas which has never had the G8JCFSDR installed, so I will try installing the G8JCFSDR on that machine and see what happens - thanks for the suggestion.
