Error installing Clients 7.5 in Solaris x86

Hi

i'm upgrading some clients from 7.1 to 7.5 but I get this error in some clients when running ./install

Do you wish to continue? [y,n] (y)
Do you want to install the NetBackup client software for this client? [y,n] (y)

This package will install Solaris/Solaris_x86_10_64 client.

NetBackup client is currently at release level 7.1.

This package will install NetBackup client 7.5.

Client binaries are located in /mnt/Netbackup/7.5/NetBackup_7.5_CLIENTS/NBClients/anb/Clients/usr/openv/netbackup/client/Solaris/Solaris_x86_10_64.

Even when I untar the packages to install I get this error only with SYMCnbclt, with SYMCnbjava and SYMCnbjre there is no problem.

pkgadd -d SYMCnbclt.pkg

I tried this in another clients and it works ok. So i've found this error in just some clients with the same instalation script.

Thanks for your help
