Hi there

I just had a problem with an installation on W11 at one of my customers:

In the application path there is an XML File [ApplicationName].xml witch contains the runtime path.

After the software starts, this xml file is modified (from launcher?), so it is no wellformed xml and no longer readable.

so starting a second time is not possible. It happens just after the start.

My workaround now is a batch file, which copies a valid xml before starting.

Attached you'll find the wellformed files and the modified file with illegal characters at the beginning.

Never seen this before.

 

Any tips?

Thank you and best regards

Stephan

Hello and Happy New Year!

 

Now after Chrismas an NewYearsEve I got an answer from my customer:

He sent me this screenshot and Protocol attached. 

The same installation works fine on other customers. 

best regards

You mean one user running app against the same server works but for second user using same server does not? It is important to identify if it is environment problem on the app user side or on the Web server side?

Hi Armeen

Yes, for most of the users ist runs without problems, but for two users I had connection problems. Downloading ist starting and stops after a few seconds with error. On retrying, the next packages are loaded, then stops again. You can repeat this game until you have success or not. Maybe on webserver side or client side there is a firewall, which closes ports. I am hosting the clod client it on an ftp server of my web provider. I do not know, which configuration my customers have.



Best regards

Stephan.

Can you reproduce this problem using PB 2022?  Older versions of PB do not support Windows 11.

Hi Armeen,

I had this the first time. I tested it on my own Win11 notebook with PB2022 and it worked fine.

But during the installation at the customer I had several problems. I had to restart the downloading procedure by launcher several times. It stopped without notifications and there were many .tmp files left.

I had this restart - problem also at another customer, who has a very fast fibreglass connection. Maybe a firewall on any side blocks this too fast access. browser says "website temporary not available". (but it was available for me)



After that still some files were missing, and I copied them manually in the PBAPPS Application directory. The application was starting once. After that the xml was no longer readable.



cloud client installation is not stable enough so far. Sometimes you have to open ports 26568-26569 to get it run. Admins don't like opening ports.



best regards

Stephan

Have you tested PB 2022? We enhanced the Cloud App Launcher.

Hi.

For some reason the xml seams to change from UTF-8-BOM to UTF-8. What would happen if your original xml is UTF-8?

By the way I see my xml are UTF-8 and not UTF-8-BOM.

Thank you Andreas,

yes it looks like BOM. But who does the insert? The original file is without BOM

Doesn't know. Haven't seen that issue in our environment.

What would happen if you make this file read only?
