I have created installers using Install4j. I am able to install the tool with these installers on both windows and linux.
but in windows, I am getting below exception...

This problem is fixed in install4j 6.1.6.
I've created a library in an attempt to handle all of the "quirks" of using Crystal Reports in a Visual Studio (VB.NET) project. I've pulled together all the elements that have presented challenges to me in the past - setting/updating parameter and formula values, printing (including page ranges), and setting logon credentials - and put them into reusable methods that all seem to work well when I generate the reports individually.
However, I've run into a scenario where I want to reuse the same report object in a loop to print multiple variations with different data sets/parameter(s) so that I can "easily" reuse the same printer settings and other options without re-prompting the user for each iteration. In this case, I'm working with an internally built
DataSet object (built by someone other than me) and my Crystal Report file's Data Source is pointing to the
.xsd file for structure.
EDIT: Forgot to mention that the report was created in CR Developer v220.127.116.118 and the VB.NET library project is targetting the 4.7.2 .NET framework and using the v13.0.3500.0 (runtime v2.0.50727) of the Crystal libraries.
My intent is/was to instantiate a new report object outside the loop, then just re-set and refresh the report's data source and parameter values on each iteration of the loop. Unfortunately, it seems that if I do it this way, the report won't correctly pick up either the parameter values, the updated data source, or both. I've been trying several variations of code placement (because I know that the order in which things are done is very important to the Crystal Reports engine), but none of it seems to work the way I believe it should.
If I instantiate a new report object inside the loop, it will correctly generate the reports for each iteration with the correct data source and parameter values. Of course, it resets all of the internal properties of my class to "default", which kinda defeats the purpose. (Yes, I know I could pass additional/other parameters to a constructor to achieve the effect, but that seems an extremely "brute-force" solution, and I'd much rather get it to work the way I have in mind).AND NOW FOR SOME CODE
Here is a pared-down/obfuscated version of the most recent iteration of the calling method (currently a part of a button click event handler). Every attempt I've made to instantiate a reusable object seems to result in some sort of failure. In this version, it loads the report and correctly passes along the parameter value, but the data source is completely empty resulting in a blank report. In other variations (I've discarded that code now), when I actually try to print/export/show the report, it fails with a COM exception:
Missing parameter values.
I've tried using the
.ReportClientDocument.VerifyDatabase methods separately, but those don't make a difference. When I check the parameters at runtime, it appears that the CR parameter/value and query results have been populated, but any method that makes any changes after the initialization just seems to "break" the report.

Okay, I believe I've found the cause of the problem, and it's one of those "quirks" I mentioned at the top of my question. The Crystal Reports engine is very particular about the order of certain events, and this is one of those cases. In my original
PrepareReport() method, I had the calls to the
.VerifyDatabase() methods executing last. This (apparently) effectively "resets" the parameters/data source, so everything I had above it was basically nullified.
So, I went back through some older code to look at how I've worked with individual Crystal Reports in the past and found that calling the
.VerifyDatabase() methods prior to attempting to set parameter and/or formula values seems to work as expected, so I moved those two lines up in the
PrepareReport() code and tried again. It all seemed to work correctly. Several tests later, and the order of execution appears to be the culprit here. Now my
PrepareReport() method looks like this:

You are running into a deadlock with the .Result call, I would suggest creating an async method in the CStatuses class and after you initialize your CStatuses class call the websocket for data.
