Problem with run app on Windows 10 64bit

[Victorio]

Hi,
I have problem with run my app on one client PC , where is Windows 10 64bit installed.
After click to exe nothing happens. I tryed exclude folder in defender, but any change.
On other PC With W10 I have not problem, also other PC with W7.
I cannot change system settings , local policy, to enable exe execution, this is an unpleasant complication if this is need, because when I install app via Teamviewer to client, I do not want interfere to his system settings.

How can I prevent this problems ? Also how can I obtain some certificate for my install packs to provide for MS windows see my app authorized and prevent notify " this app is not...." I mean, this is payed service , but I am not sure, how implement this certificate to Alaska Xbase apps.

Maybe you ran into the Windows Creator's Update-problem. What happens if you change the screen resolution/scaling? Is that a high resolution monitor with > 100 percent scaling? There's a fix for that kind of problem from Alaska, even for 1.9SL1.

Hi Tom !,
I examine only compatibility change to W8,W7,WXP, noeffect, but resolution I not test.
My Alaska licence is 2.0 build 554 , with express + sql Express from Boris, and also xb2net.

Now I cannot test it, because client is off office. He have Windows 10 64bit , procesor i5, but this can not problem (some time ago was problem with quick microprocessors and CA Clipper, for it I used time loop to slow processor for run Cliper programs )

Are symptoms as application not run ? it is not in processes active, that looks to windows blocked run it.
I cannot simulate it, this is problem,

[Tom]

Yes, the symptom is a failing app. You may get a XPPFATAL.LOG in the application folder. Check it out.

Thank's, I forget look error log file....

Hi,

It seems as this is the cause of something I have on my system.

Code: Select all

FATAL ERROR LOG 
Not recoverable Error!
SYS Thread-ID: 216 
Module: EH
Error Codes: EH: 900 Sub: 0(0) OS: 0 XPP: 0
Call Stack of Thread 1 (216):
Call Stack of GUI Thread (1200):
File: C:\xppfirst\count.exe
TimeStamp: 20180112 08:57
End of FATAL ERROR LOG.

Strange about this problem is that I have it maybe once a week when I start my PC. After restarting the problem is solved. I never change my resolution or scaling.

In the PDR 6904 of Alaska there is the following:

For some reason Xbase++ GUI applications fail to start on some Windows 10
operating systems with version 1703 (Creators Update, build# 15063).

In most cases a xppfatal.log is created which states
EH: 900 (Not recoverable Error!) to be the reason for the abortion.

Xbase++ Textmode applications are not affected.

According to the current state of our analysis the problem seems to be
related to high resolution high dpi settings of Windows 10 Creators Update
installations only.

The proposed solution is the following:

Try to change the custom scaling factor. What scaling factor to use can
not be predicted.

In my case a restart without changing anything solves the problem.

I have two monitors on 1920x1080 and scaling on 100%.

[skiman]

Changing the scaling to 125% didn't help.

Changing the resolution to a lower resolution without restarting the PC solved the problem. The application started correctly. I closed the application and changed the resolution again to the original settings, and the application started also without problem.

yes ... but only as long as you do not logout !

other is to change DRIVER Resolution
1920 x 1080 @ 125 % -> 1600 x 900

in Alaska Newsgroup you can find ScreenRes.ZIP
you can use it with a Xbase++ VIO App once before start your GUI Apps.

[Victorio]

I can confirm, that screen resolution is problem.
Client run app on notebook with resolution 1920/1080 and font 125% !,
when change to lower 1600/900 program start normally.

As client tell me, he has problem also with other not my application, and solve it with parameters of link Rewrite hi DPI tp System, but with this blink screen.

Jimmy, I found Screeenres.zip on Xbase newsgroup and there is screenres.dll, but this thread is from 2007 year. Is this you mean and how use it ?

[skiman]

Hi Jimmy,

You wrote

yes ... but only as long as you do not logout !

The strange about this is that i can work some days without any problem, and sometimes in the morning it isn't working on the same PC with the same resolution.

other is to change DRIVER Resolution
1920 x 1080 @ 125 % -> 1600 x 900

This didn't work on my system.
