Hello.

All our paid licenses are perpetual. And they are all scoped to specific version range (more precisely, release date range). When purchasing, you could choose between no upgrade assurance (so only the versions up to the current one are covered; this was possible in 2021 but the option is no longer available), or with an upgrade assurance term, which can be 1, 2, 3, 4, 5 or 6 years (and can be extended while still valid). With upgrade assurance, future versions released during the selected period are also automatically covered without further payment.

I can give you the available purchase options but I was not able to identify you - please send me an email, to sales09 (at) opclabs.com. If you have an older license then there will be some version upgrade discount.

Best regards

My license no longer works was created by PhilippeGU
Hello,
I need to update an old .NET application (migration to .NET 10) that uses QuickOPC.
Until now, I was using version 5.80.347, but after upgrading to version 5.83.1134, my license no longer works.
Code:
[code]"Multipurpose(Dropped1).AllPurposeStations": 1,   "Multipurpose(Dropped1).CallerRestrictions": [   ],   "Multipurpose(Dropped1).ClientLRUSizeLimit": XXXXXXXXXXXXX,   "Multipurpose(Dropped1).ExtraRuntimeStations": XXXXXXXXXXXXX,   "Multipurpose(Dropped1).Hidden": 0,   "Multipurpose(Dropped1).ID": "Multipurpose",   "Multipurpose(Dropped1).IssuerName": "OPC Labs",   "Multipurpose(Dropped1).NotAfter": "1601-01-01T00:00:00Z",   "Multipurpose(Dropped1).NotBefore": "1601-01-01T00:00:00Z",   "Multipurpose(Dropped1).OptionRestrictions": [         "-EasyUACertificateManagementClient",         "-EasyUAFileTransferClient",         "-EasyUAGlobalDiscoveryClient",         "-LiveMapping",         "-Reactive",         "-RtdServer",         "-StreamInsight",         "-UAComplexData"   ],   "Multipurpose(Dropped1).PlatformRestrictions": [   ],   "Multipurpose(Dropped1).ReleaseDateCovered": "2024-08-12T00:00:00Z",   "Multipurpose(Dropped1).RunOnServer": 1,   "Multipurpose(Dropped1).RunTimeLimit": "-00:00:00.0010000",   "Multipurpose(Dropped1).SerialNumber": XXXXXXXXXXXXX,   "Multipurpose(Dropped1).SubjectName": " XXXXXXXXXXXXX ",   "Multipurpose(Dropped1).TopicLRUSizeLimit": 2147483647,   "Multipurpose(Dropped1).Type": "Professional; Single Developer + Runtime Free License",   "Multipurpose(Dropped1).VersionNumberCovered": 530
[/code]

During my last purchase in 2021, I understood that my license was perpetual. I did not expect it to expire or to be restricted to specific product versions.
Following my recent upgrade, I have noticed that my existing license is no longer valid with the newer QuickOPC version.
Could you please advise on the available options to obtain a new valid license ?

best regards
