HI and welcome to Arturia forums.
Keep in mind, that you only can use Arturias applications from before V-Collection 5 as the applications was changed then.
I think you should be able to use ASC. But in any case, then you should be able to download all the applications for your V-Collection 4 here:
https://www.arturia.com/support/downloads&manualsYou shall use applications from 2015. Click the green "SHOW ARCHIEVE" buttons for a product and scroll down the list of older versions.
You can use the latest Spark 2 version.
For Analog Lab you can install both the old version for your old applications alongside the latest Analog Lab. ut you will not be able to open your full applications inside the new Analog Lab 4. The new Analog Lab have a Soundstore and some presets from newer applications. So perhaps you wan't it anyway. The soundstore presets can't be used in your old applications.
If you can't download and install your old applications, then please contact Arturia support.
Be sure you activate through Arturia Software Center. eLicenser was abandonded in V-Collection 4.
Hope this helps.
