Crystal Reports - 客户端的 temp_{}.rtp 文件出错

Question

I have a C# application running on the client side, that uses the Crystal Reports for generating and printing reports and billings of sorts using a local database.

The problem is, after installing a version, the program started returning the error "error in tmp_XXX..._{XXXX...}.rtp. Failed to retrieve from Database". Thing is, an older version of the applications was working properly.

What I have tried:

• Installing the same version on my machine and another developer machine. It worked fine on both
• Tested running a Select, Insert, Alter and Update command using the application, both on client and developer machine. It worked fine on both cases
• Tested the Oracle connection with another program, namely MySQL Workbench. The connection was succesfully
• Reinstall the CR13SP27MSI32_0-10010309 (SAP Crystal Reports runtime engine for .NET Framework x32)
• Install the CR13SP27MSI64_0-10010309 (SAP Crystal Reports runtime engine for .NET Framework x64)
• Reinstall the application
• Wipe clean the temp folder(C:/users/.../temp)

Client side information:

• Windows 11
• No.Net Framework found on "Alter and Remove Programs". (Not sure if relevant)

I am out of ideas on what more to do.

Answer 1

After hitting my head on the wall(figuratively, of course), I notice that the client did not have administrator permission to run the MSI files.

All that I needed was to do was the following:

1. Open the CMD as Administrator(Somehow, the client could use the CMD as Administrator, but not the MSI)
2. In the command prompt, input: msiexec /i "path\setup.msi"
3. Press Enter
4. Run the install as usual

Once done, all worked fine.
