Funny,the same question was asked yesterday in a different forum.
Here is what I found when checking a SiS 11.32 system:
<SiteScope>\conf\license
..
04/28/2016 06:06 PM 9,917 lic.txt
06/03/2016 12:40 PM 1,418 lic_v2.txt
..
lic.txt is a file which contains all instant-on (trial) licenses,
lic_v2.txt contains the license I added when importing the SiteScope license from after installing SiteScope,
although converted to XML format:
..
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<LicenseList>
<RawLicense type="OvKey4">9BLE D99A H9PY KHX2 VAC5 HWSB Y9JL KMPL B89H MZVU DXAU 2CSM GHTG L762 VLZ4 WBZ9 LNVT D5K9 EFVW TSNJ 9CTM MXGS KP2K YGG8 29SJ AWPR H2PE 97UM C23A H6GA NLNS DKWK JV8E 9438 VK4Q T4GA 7M8K HSPU 59G8 F8XA 4NNA 9GEB CZU7 WE43 EXAD 7L55 VSR3 KFEZ YJ96 4C6B"Freemium InstantOn License HPSiS 11.30"</RawLicense>
..
When I stop SiteScope and remove lic_v2.txt, it gets re-created, but now with the content
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<LicenseList>
<RawLicense type="OvKey4">9BLE D99A H9PY KHX2 VAC5 HWSB Y9JL KMPL B89H MZVU DXAU 2CSM GHTG L762 VLZ4 WBZ9 LNVT D5K9 EFVW TSNJ 9CTM MXGS KP2K YGG8 29SJ AWPR H2PE 97UM C23A H6GA NLNS DKWK JV8E 9438 VK4Q T4GA 7M8K HSPU 59G8 F8XA 4NNA 9GEB CZU7 WE43 EXAD 7L55 VSR3 KFEZ YJ96 4C6B"Freemium InstantOn License HPSiS 11.32"</RawLicense>
</LicenseList>
This is also reflected in the SiteScope -> Preferences -> Licenses section, now it's downgraded to Community Edition
So in anutshell, at least for SiS 11.32, <SiteScope>\conf\license\lic_v2.txt keeps the license one has imported.
Depending on the license it also might be in lic.txt
Prior to 11.32 it seems this was done differently, I was at least able to find a folder which keeps a list of license files used to import:
<SiteScope>\tmpImportLicense
06/03/2016 01:22 PM 9,504 Lic_11.2x_bac17.txt
06/03/2016 01:22 PM 10,178 Lic_11.2x_bac17.txt_2016.06.03.13.22.36
12/11/2015 10:58 AM 9,504 Lic_SIS-15M^11.20_swvm403.dat
12/11/2015 10:58 AM 10,178 Lic_SIS-15M^11.20_swvm403.dat_2015.12.11.09.58.24
The second file, "Lic_11.2x_bac17.txt_2016.06.03.13.22.36" is the one I imported (although the filename was Lic_11.2x_bac17.txt at the time of the import), and it shows
..

..
the other one contains the same list of keys, but all the comments have been removed.
BTW, the SiS 11.32 system also keeps the licenses imported in <SiteScope>\tmpImportLicense
Hope this helps
