I am really sorry but I am not planning to work on GameEx Evolution any time soon. Please try GameEx or an alternative front end. Thank you.

Hi.

No worries, i would hope someone had this problem before and could share the solution to it.
I´ll try myself and if i find the resolution, i´ll post it here.

Best regards.

Google AI shows the following - check for special characters in filenames or paths:

The "Input string was not in a correct format" error in Windows environments typically indicates that an attempt was made to convert a string to a different data type (e.g., integer, double, date) but the string's content did not conform to the expected format for that conversion.

Common causes of this error include:

Incorrect Data Formatting:

Non-numeric characters in numeric fields: Attempting to convert a string containing letters, symbols, or spaces into a number.

Incorrect decimal or thousand separators: Using a decimal or thousand separator that differs from the system's regional settings.

Invalid date formats: Providing a date string that does not match the expected date format (e.g., mixing text and numbers in date fields, or using a format not recognized by the system).

Regional and Language Settings:

Mismatched language settings: Applications or services expecting a specific language/culture (e.g., "en-US") for data processing, while the system or application is configured for a different language that uses different formatting conventions.

Empty or Null Strings:

Attempting to convert an empty string or a string containing only whitespace to a numeric or other specific data type.

Data Size or Range Issues:

Trying to convert a string representing a number that is too large or too small for the target data type (e.g., trying to fit a very large number into an integer variable).

Special Characters in Text Fields:

Including unsupported or unexpected special characters in fields like invoice numbers, descriptions, or passwords, which can cause issues during data export or processing.

Application-Specific Issues:

Bugs or misconfigurations within specific applications (e.g., accounting software, reporting tools) that lead to incorrect data handling or parsing.

Permissions issues preventing an application from properly accessing or processing data.

Windows Updates:

In some cases, specific Windows updates can introduce compatibility issues that affect how applications handle data conversions, leading to this error.

I will try some of those options, have to virtualize the os first for testing purposes.

Thanks.

[gorgeousjorge]

Can someone point me into what the final line points to?
This one "Headsoft.Tools.LogFile"

Here is this log file?

Thanks.

[Draco1962]

No log file attached to review.

[gorgeousjorge]

I mean, where do i find that log? The one in the screenshoot in my first post.

Ok i think i´ve found it.
 

[GAMEEX_EVOLUTION].log

[gorgeousjorge]

Just found what`s going on after 4 hours of virtual machines testing:

Internet.

If i disable the adapter or disconnect the cable no error message. So i assume it os something due to my account on your servers?

Double check the login and password, all is ok.

Can you provide some feedback?

[Draco1962]

I am not certain if that is the cause or not. Certainly not anything to do with your forum credentials. I do not use the software so have minimal triage experience with it. Since Tom noted that he is not actively planning any work on GameEx Evolution anytime soon, unless someone else has experienced the same error and has reported a solution, you may be better off trying GameEx. Sorry.

[gorgeousjorge]

Did the log i provided give you any clue?

[Draco1962]

It did not other than the error occurring right after 

11-Sep-25 22:38:39: Downloading '[Console] Nintendo NES (VirtuaNES)' Assets
11-Sep-25 22:38:39: ERROR @ OnLoadDataDoWork (SystemData)

Have you tried disabling NES emulator setup to see if that remedies it? Other than that, I am not sure I am going to be of any help.

[gorgeousjorge]

I´m currently installing on a fresh stock vm. Doing updates.
Next game ex evolution with no credentials, no emulators no nothing. Stock.

Windows VM fresh Install, all updates done.

[Draco1962]

So seeing the same errors?

[gorgeousjorge]

Yep, on a fresh windows install, no credencials inputed. Must be something else.

[Draco1962]

What version of .net is installed? Log shows Windows 10 Pro 

[gorgeousjorge]

Hi.
Just ran this command to get the versions installed listed:

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse | Get-ItemProperty -Name version -EA 0 | Where { $_.PSChildName -Match '^(?!S)\p{L}'} | Select PSChildName, version

Also checked the file version.
I´m up to 4.8

[Draco1962]

Still getting the same errors after the update? Please note what errors you see when you report back. Thanks.

[Tom Speirs]

I respect your commitment but I doubt it can be fixed without a code update from me. Sorry.

[gorgeousjorge]

Was there any update on your part Draco1962?

No worries Tom Speirs, just glad i can give any help.

For context i run win10 pro and i only make updates yearly more or so, the pc´s wich gameex is installed don`t change much in terms of software.
I run backups with Macrium Reflect and my first action was to roll back to 4 months ago, the issue persisted.
In the meantime i´ll just block it with the firewall as a workaround.

Regards.

 

[Draco1962]

No changes made be me. I was just asking if you were seeing the same issues after you updated .net. 

I have no more suggestions at this time unless Tom updates the code which is not likely at this time.

I suggest as has been suggested before to put your time into GameEx or another frontend.

[Tom Speirs]

Thanks for troubleshooting. It might be getting a bad response from my server. It could be something has changed online. I did setup a new server a couple of months a go. I could have missed something.

Although still a little pointless using GameEx Evolution as it is not getting updates. I should probably remove the download. if i get more posts like this I will.

You did not say if you were already using the product and it suddenly broke or if it is a new install?

[Tom Speirs]

i just downloaded it as a fresh install. Looks like it is definitely something on the server. It is not even downloading the MAME logo. It could have an old hardcoded URL. Again, I am not planning on working on it so I am going to remove the download. It still looks very pretty though.

[gorgeousjorge]

First of all, thanks for your inputs on this.
I did not installed the .net framework, just run that code to check wich versions were installed.
Gameex Evolution worked always fine, i installed it several years ago so no new installs, 4 years or more ago, and it was only now that the bug presented itself.
Mind you that last time i fired up the software was 4 months ago or so, and then when i started this thread, so something in that time frame must have changed.

Please don`t remove it, i like it much more than the "normal" gameex and i bet a lot more people are on the same pace.
It´s just a "bug" if you press ok on the error it will go away and the software works like it should, it`s just my "nerdiness" on the subject eheheheh.
