Dynamics 365 BC Web Client does not working

aceX · 2019-05-24

Hi,

I've installed Dynamics 365 BC on a couple of machines and everything was ok. On my local computer where I don't have any other Dynamics programms, the web client is not working. But this time wile installing Dynamics 365 BC for the first time, I've forgot to include Web Client.
After the installation was completed, I've start the installation once more and from Add remove components and aded the Web Client.
When instalation finalized I'm getting: Web Client is not installed, Fatal Error has occured.
Then I installed the Web Client from .msi file from instalation folder and every thing went ok.
After that if I restart the default installation and start Repair, installation completes successfully without any error or warning.
What ever I do, the error is always the same:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid

Possible problems:

- Duplicate or malformed key in the config.
- Missing Installation Components

Thank you @Arhontis for your time. I've already checked and try the possible solutions from the links you send me and much more. I've never find out in which .config file I should set the parameter

which is contained as resolution in your first link.
However, I think this parameter exist only in older Dynamics versions.

Best Regards

Why don’t you uninstall and and restart the installation all over again?

I've tried that @Developer101 for more than 10 times

.

I'm uninstaling the program from installation wizard and also I'm removing all register changes and IIS changes. After re-installation it's all the same. I've checked all WIndows Features which need to be included (or excluded) and still no result

Found some more info on the error. Since the Config Source on your error is somewhat empty, it makes sense to maybe the service user don't have access to the config files, as stated here:

https://stackoverflow.com/questions/9216158/the-requested-page-cannot-be-accessed-because-the-related-configuration-data-for

Or the registration of iis is not correct as it is also stated on the above post.

It is pretty extensive and provides multiple solutions...

I hope you haven't tried those before and solve your issue...

Thank you very much @Arhontis, for your time. I was extremely limited with the time, so I resolve this with windows reinstall (using image backup) and I'm unable to test your solution will it work. If I see this problem again (honestly I hope not) I'll try this and write here for the result.

Best Regards
