  How can Hi I get my cs5 to start working again? Suddenly, the serial number has become invalid

  If you purchased CS5, you should have the case (with serial number) and the original dvd or if you have purchased online, this serial number will be in your adobeID profile.

  If you have downloaded CS5 a few years back, you reinforced the installer?

  The serial number should work - contact adobe if you activation problems - it could be you have CS5 installed on more than two computers, the license only allows two facilities - if you are trying to install on a third computer, you will see a prompt to disable the software on other computers.

• What happens IF we replace the default certificates for vCenter 5.1?

  Does anyone have specific vmware documents indicating what happens IF we replace the default certificates for vCenter 5.1 SSO, inventory, Web Client etc... services?

  I found this below at page 19 of https://www.vmware.com/files/pdf/products/vCenter/VMware-vCenter-Server-Single-Sign-On.pdf

  Certificates update

  When you install the vCenter Single Sign-On, each component that registers with it - including

  vCenter Single Sign-On himself - uses SSL to communicate between components and saved solutions.

  By default, SSL certificates are generated automatically by VMware installation and upgrade process

  and are sufficient for the operational security for most VMware customers.

  Some clients prefer to use their own self-signed or purchased SSL certificates. A tool has been developed to

  help the insertion of these certificates after vCenter Server installation. Because of the additional knowledge

  required to create and install self-signed certificates, we recommend that you review the following knowledge of VMware

  basis of articles:

  "Deployment and using the tool to automate SSL certificate.

  (VMware 2041600 knowledge base article)

  "Generation of certificates for use with the VMware Certificate SSL automation tool"

  (VMware 2044696 knowledge base article)

  In 10 years your vCenter starts (because of expiry of the certificate).

  Your users will see pesky warnings of SSL certificate when connecting components.

  Apart from that all traffic is always secure and encrypted with certificates by default, you have simply a chain of trust for them.

• The SSO authentication: the SSL certificate is unknown

  Hello

  I'm trying to configure orchestrator solution to use SSO for authentication. Although the vCenter certificate is installed and displayed in the trust to SSL Manager, I get the following error:

  The SSL certificate is unknown. You can fix this in the SSL Certificate tab.

  Tried to reinstall the certificate, restart the device - without success. Username and password are correct.

  I use Version of the device: 5.5.0.0 build 1282845, vCenter 5.5.0, 1476327.

  How can I solve this problem?

  By "vCenter certificate is installed," do you mean Certificate SSL VC (imported from https://[vc-ip]:443)?

  For SSO authentication, you must also import the UNIQUE https://[sso-ip]:7444 authentication certificate
