first of all, this is not possible

$hash{'HKEY_LOCAL_MACHINE'}{'SOFTWARE'}{'Vendor'}{'Product'}{'CurrentV
+ersion'}{'
+Tokens'}{'Encotone'}{'SerialNumberUserAttribute'}=12345;
$hash{'HKEY_LOCAL_MACHINE'}{'SOFTWARE'}{'Vendor'}{'Product'}{'CurrentV
+ersion'}{'
+Tokens'}{'Encotone'}{'SerialNumberUserAttribute'}{'LanMan'}{'Value'}=
+"";

a hash-entry can't be 12345 and a hash-ref to {'LanMan'}... at the same time.

consider ... {value}=12345

> Anybody have any ideas?

first step should be to build the mainpath as string with splits and joins.

then eval this string to autovivify this hash, and assign a ref to a $subhash to it.

This $subhash -ref can be populated now with all entries which come.

UPDATE

if you don't like evals build the HoH-path in a loop (line 163)

  DB<160> $line='HKEY_LOCAL_MACHINE\SOFTWARE\Vendor\Product\CurrentVer
+sion\Tokens\Encotone\SerialNumberUserAttribute=12345'

  DB<161> ($path,$value)= split /=/, $line

  DB<162> $subhash=$hash={}

  DB<163> $subhash = $subhash->{$_} = {} for split /\\/,$path

  DB<165> $subhash->{value}=$value

  DB<166> $subhash->{LanMan}{value}=""

  DB<167> $subhash->{LanMan}{type}="REG_SZ"

#... and so on for all sub-entries ...

  DB<168>  $hash
 => {
  HKEY_LOCAL_MACHINE => {
        SOFTWARE => {
              Vendor => {
                    Product => {
                          CurrentVersion => {
                                Tokens => {
                                      Encotone => {
                                            "SerialNumberUserAttribute
+" => { LanMan => { type => "REG_SZ", value => "" }, value => 12345 },
                                          },
                                    },
                              },
                        },
                  },
            },
      },
}

now repeat these steps for all paths!

HTH

UPDATE

this might delete older sub-structures from previous paths

DB<163> $subhash = $subhash->{$_} = {} for split /\\/,$path

so better do

$subhash = $subhash->{$_} //= {} for split /\\/,$path
