We develop applications in C# using QC2DChart. The applications work great on our WinXP 32bit workstations. Currently we're switching to Win7 64bit. I just tried to install one of our apps using QC on a win7 64bit workstation. But when I want to open a QC graph there is the message in the control that I have to resubcribe or QC can not find the license file.
Do you have an idea how I have to setup QC so that it works on Win7 64bit?
Nothing special needs to be done to get the software to work under Win 7. Your application program cannot find the license file. So, where did you place the license file on the target computer, and what location are you specifying for the license file ( using ChatView.SetLicensePath) in your application program?
We strongly recommend you upgrade to the current version of the software (Rev. 2.0). In addition to many new features, we eliminated the license file from the software. See the product description at: http://www.quinn-curtis.com/QCChart2DProdPage.htm .
Thanks for your reply. I just discussed with my boss this morning to purchase the latest version of qc. This would be the best solution if you eliminated the license file. I just checked. Inside our app we nowhere set the license file path by code. I think by default qc is checking in c:\windows\system32 for the lic file. There it is installed when you setup qc. On the 64 bit station the license file is placed in system32 and sysWOW64 too. I guess because I targeted our app on x86 the default path (system32) can not be reached by the app. But I couldn't verify this so far.
The placement of the license file in the Windows/System32 folder is from the installation of the full developer version of the software. For an application program, place the license file in the application folder holding your exe. Specify that folder in the SetLicensePath. This is all described in the manual which came with the software, and in examples which came with the software. See the tutorial chapter of the manual, "Using QCChart2D for .Net to Create Windows Applications".
Note to most users: this applies only to Rev. 1.6 and earlier versions of the software. Revisions later than 1.6 do not use a license file.
